Drinking olive oil: a health and beauty elixir or celebrity fad in a shot glass?

<p><em><a href="https://theconversation.com/profiles/hazel-flight-536221">Hazel Flight</a>, <a href="https://theconversation.com/institutions/edge-hill-university-1356">Edge Hill University</a></em></p> <p>In the ever-changing world of wellness trends and celebrity endorsed health fads there is a new trend on the scene: daily olive oil shots.</p> <p>Celebrities such as <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/">Kourtney Kardashian</a>, Beyonce, Gwyneth Paltrow and <a href="https://www.womanandhome.com/life/news-entertainment/jennifer-lopez-credits-her-grandmas-crazy-beauty-secret-for-glowing-skin-and-chances-are-you-already-have-it-at-home/">Jennifer Lopez</a> all extol the virtues of swigging extra virgin as well as slathering it on their skin, crediting olive oil for their glowing complexions.</p> <p>Lopez even based her JLo Beauty brand around the kitchen staple, claiming that her age-defying looks were not the result of botox or surgery but the family beauty secret: <a href="https://graziamagazine.com/us/articles/jennifer-lopez-skincare-routine/">moisturising with olive oil</a>.</p> <p>And she’s in good company. Hollywood star <a href="https://jnews.uk/goldie-hawn-swears-by-olive-oil-for-perfect-skin-at-76-best-life/">Goldie Hawn reportedly drinks olive oil</a> before bed and uses it topically as a moisturiser, while <a href="https://www.redonline.co.uk/beauty/a31184313/julia-roberts-olive-oil-hair-skin/">beauty icon Sophia Loren</a> really goes to town by bathing in the stuff.</p> <p>While these celebrities swear by the skin beautifying properties of olive oil, some skin types should <a href="https://scholarhub.ui.ac.id/cgi/viewcontent.cgi?article=1182&amp;context=jdvi#:%7E:text=Background%3A%20Dry%20skin%20or%20xerosis,water%20in%20the%20stratum%20corneum.">give it a swerve</a>.

Viral videos show influencers tossing back shots of cult olive oil brands, and proclaiming a wide range of health benefits from improving digestion to clearing up acne.</p> <p>Celebrity and influencers are sold on liquid gold but what about the rest of us? Can drinking olive oil really work on miracles for our health?</p> <h2>The benefits of olive oil</h2> <p>There’s no doubt that olive oil is full of good stuff. It’s high in polyphenols and antioxidants, which have protective qualities for the body’s tissues. It’s also a rich source of essential fatty acids, including oleic acid, which is known for <a href="https://foodrevolution.org/blog/olives-and-olive-oil-benefits/#:%7E:text=Compared%20with%20olives%2C%20olive%20oil,in%20polyphenols%20and%20antioxidants%2C%20however">lowering cholesterol</a> so reducing the chances of heart disease.</p> <p>Research has found that the inclusion of olive oil in the diet shows encouraging effects in a variety of <a href="https://doi.org/10.3390%2Fnu11092039">inflammatory and medical diseases</a> and can <a href="https://doi.org/10.3389%2Ffnut.2022.980429">support weight management</a> if used correctly.</p> <p>Replacing butter, margarine, mayonnaise and dairy fat with olive oil has been linked to a <a href="https://doi.org/10.1016%2Fj.jacc.2021.10.041">lower risk of mortality</a>. There’s also evidence to suggest that the protective compounds in olive oil may help <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0261649">guard against cancer</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10376491/">dementia</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/29141573/">support the liver</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7916323/">and kidneys</a>.</p> <p>But none of this is new information to health professionals. The health benefits of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7466243/">extra virgin olive oil</a> are <a href="https://doi.org/10.3390%2Fnu11092039">well researched</a> and nutritionists have promoted olive oil as a swap for saturated cooking fat for years.</p> <p>After all, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7536728/">Mediterranean diet</a> has been touted as one of the healthiest diets in the world for decades. The diet itself can vary from region to region, but <a href="https://doi.org/10.3390%2Fnu15092127">virgin olive oil</a> is a <a href="https://doi.org/10.3390%2Fnu11092039">consistent element</a>. It’s used as the <a href="https://www.themediterraneandish.com/cooking-with-olive-oil/">main source of cooking fat</a> and included in everything from salad dressings to bread.</p> <figure><iframe src="https://www.youtube.com/embed/krFcE5IPT7g?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Can fat be healthy? Yes and no</h2> <p>Fats are crucial for a balanced diet, aiding in the absorption of fat-soluble vitamins A,D,E,K and enhancing the nutritional value of meals.</p> <p>However, fat of any kind is also dense in calories and excessive consumption <a href="https://doi.org/10.1159/000336848">can lead to weight gain</a>. According to the <a href="https://www.who.int/news/item/17-07-2023-who-updates-guidelines-on-fats-and-carbohydrates">World Health Organization</a>, to prevent unhealthy weight gain, adults should limit their intake of fat to 30% of total energy intake with no more than 10% coming from saturated fats.</p> <p>Two tablespoons of olive oil – the standard amount in the shots taken by celebrities and social media influencers – contain 28g of fat (238 calories) and 3.8g of saturated fat equating to <a href="https://fdc.nal.usda.gov/fdc-app.html#/food-details/171413/nutrients">19% of the recommended daily intake</a>.</p> <p>That daily shot of extra virgin, then, might not be the best idea. Adding small amounts of olive oil to meals throughout the day is a more balanced – and appetising – approach to incorporating healthy fats into your diet.</p> <p>But what about Kourtney Kardashian’s <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/#:%7E:text=First%20things%20first%2C%20it's%20recommended,a.m.%20(every%20other%20day).">claim that</a>: “It’s recommended to consume extra virgin olive oil in the morning on an empty stomach so the oil can coat your system and neutralize your stomach walls for optimal benefits?”</p> <p><a href="https://www.oliveoiltimes.com/briefs/consuming-olive-oil-on-an-empty-stomach-health-benefits/91503">Some brands</a> have also echoed the idea that consuming olive oil on an empty stomach offers unique health benefits. But no. There’s no scientific evidence to suggest this is true.</p> <p>For a healthy but more satisfying snack, Kourtney might try including a handful of olives into her daily diet. Olives offer the same rich array of nutrients, including vitamins E, A and K, alongside essential minerals such as iron, calcium, magnesium, potassium and amino acids.</p> <p>Unlike olive oil, olives have the added benefit of a high fibre content. The combination of fat and fibre enhances feelings of satiety, making olives a nutritious addition to the diet.<!-- Below is The Conversation's page counter tag.

Should you be worried about the amount of coffee or tea you drink?

<p>Before you reach for that cup of coffee or tea, have you ever thought about whether that caffeinated beverage is <a href="https://cosmosmagazine.com/health/body-and-mind/debunks-vices-coffee-caffeine/">good or bad for you</a>?</p> <p><iframe title="Vices: Is coffee good or bad for you?" src="https://omny.fm/shows/debunks/vices-is-coffee-good-or-bad-for-you/embed?style=Cover" width="100%" height="180" frameborder="0"></iframe></p> <p>Most of us will drink coffee or tea each day.</p> <p>It helps keep us alert, especially in a world of the nine-to-five grind. Some workers rely on caffeine to get them through shift work and night shifts.</p> <p>Many, like me, would just collapse in a heap if it weren’t for that liquid black gold to keep us peppy in the morning.</p> <h2 class="wp-block-heading">What is caffeine?</h2> <p>To get a better picture of how coffee or tea affects us, let’s examine the active ingredient: <a href="https://cosmosmagazine.com/podcast/huh-science-explained-stirring-the-science-of-caffeine/">caffeine</a>.</p> <p>Caffeine is a <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/caffeine" target="_blank" rel="noopener">drug</a>. It’s a white, odourless substance known to chemists as 1,3,7-trimethylxanthine and is made up of 8 carbon, 10 hydrogen, 4 nitrogen and 2 oxygen atoms.</p> <p>Caffeine occurs naturally in coffee beans, cocoa beans, kola nuts, and tea leaves.</p> <p>It is an adenosine antagonist, blocking the A1, A2A, and A2B receptors in the brain and body to promote wakefulness. Normally, adenosine (a chemical compound with a similar 3D structure to caffeine) binds to its receptors, slowing neural activity and making you sleepy.</p> <p>When caffeine, instead, binds to the receptors, adenosine is blocked and brain activity speeds up, making you feel more alert.</p> <h2 class="wp-block-heading">History lesson</h2> <p>Tea and coffee are the most common way for humans to get their caffeine fix.</p> <p>Drinks made using coffee beans date back more than a thousand years to the coffee forests of the horn of Africa.</p> <p>Legend says that, around 800 CE, an Ethiopian goat herder named Kaldi noticed his goats were energetic and didn’t sleep when they ate the coffee beans. Coffee then spread eastward to the Arabian Peninsula, reaching Yemen in the 15th century, and Egypt, Syria, Persia and Turkey in the 1500s. From their it made it to Europe and eventually the whole world.</p> <p>But caffeine is also present in other beverages like tea, cola and even some foods like chocolate.</p> <h2 class="wp-block-heading">Is it bad for you?</h2> <p>Given how prevalent the drug is, are there negative side effects we should be worried about?</p> <p>For one thing, it is an addictive substance. And the more you drink, the more you need.</p> <p>“Our body tends to adjust to a new level of consumption,” Kitty Pham, a PhD candidate at the University of South Australia and expert in nutritional and genetic epidemiology, tells <em>Cosmos</em>. “Your body does develop a tolerance to the caffeine. So, you start to need to drink more and more to feel the same effect as before.”</p> <p>Caffeine can also act as an anxiogenic – a substance that can trigger heightened levels of anxiety.</p> <p>Pham notes some risks associated with too much caffeine consumption over a long period of time.</p> <p>“Greater than 6 cups per day, we did see an increase in dementia risk,” she notes. “There’s also some research on how it might increase your cholesterol. There’s a substance in coffee called cafestol that can regulate your blood cholesterol. If you’re drinking too much coffee, it might be increasing your cholesterol. So, there are risks, but often they are at really high consumption.”</p> <h2 class="wp-block-heading">What’s the limit?</h2> <p>So, how much caffeine is too much according to science?</p> <p>“That’s, the million-dollar question, isn’t it?” Pham laughs. “There’s a lot of varying research on it. It’s hard to tell a definite limit. But generally, most studies really agree that one to two cups of coffee, or an equivalent of 100 to 200 milligrams of caffeine is safe and okay.”</p> <p>The average cup of coffee has about 100 mg of caffeine. On average, instant coffee with one teaspoon of powder contains about 70 mg of caffeine, while a coffee pod has 60–90 mg.</p> <p>Other drinks containing might have even more caffeine, making it important to monitor your consumption more carefully.</p> <p>A 355 mL can of Red Bull energy drink has more than 110 mg of caffeine. Meanwhile, an average bar of dark chocolate has about 70 mg of caffeine.</p> <p>Many people are moving away from coffee to drinks like tea and matcha which may have <a href="https://cosmosmagazine.com/health/flavonoids-black-tea/">additional</a> <a href="https://cosmosmagazine.com/health/tea-drinkers-may-well-live-longer/">health</a> <a href="https://cosmosmagazine.com/health/black-tea-mortality-risk/">benefits</a>. A 100-gram cup of black tea has only about 20 mg of caffeine, while matcha can have 140–170 mg of caffeine!</p> <p>“Looking at the US, they usually recommend less than 400 milligrams. So overall, moderation and keeping your consumption to one to two cups – that’s what I’d recommend.”</p> <p>Now that I’ve written about caffeine, I think I need another cuppa. It’s only my second of the day, I swear. </p> <p><em>Image credits: Getty Images </em></p> <div> <h3><em><a href="https://link.cosmosmagazine.com/JQ4R"><noscript data-spai="1"><img decoding="async" class="alignleft size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/ret_img/cosmosmagazine.com/wp-content/uploads/2023/04/Apple-Podcasts.svg" data-spai-egr="1" alt="Subscribe to our podcasts" width="300" height="54" title="should you be worried about the amount of coffee or tea you drink? 2"></noscript></a><a href="https://link.cosmosmagazine.com/JQ4U"><noscript data-spai="1"><img decoding="async" class="alignleft size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/ret_img/cosmosmagazine.com/wp-content/uploads/2023/04/Spotify.svg" data-spai-egr="1" alt="Subscribe to our podcasts" width="300" height="54" title="should you be worried about the amount of coffee or tea you drink? 3"></noscript></a></em></h3> </div> <p><em><!-- Start of tracking content syndication.

Christmas drinks anyone? Why alcohol before bedtime leaves you awake at 3am, desperate for sleep

<p><em><a href="https://theconversation.com/profiles/madeline-sprajcer-1315489">Madeline Sprajcer</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>; <a href="https://theconversation.com/profiles/charlotte-gupta-347235">Charlotte Gupta</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>; <a href="https://theconversation.com/profiles/chris-irwin-249481">Chris Irwin</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/grace-vincent-1484516">Grace Vincent</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>, and <a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>You’ve come home after a long day at work, you have dinner, put the kids to bed, and then you have your usual nightcap before drifting off to sleep. Or, perhaps you’re at the pub for the work Christmas party, and you think you’ll just have one more drink before heading home.</p> <p>That last drink might help you fall asleep easily. But your nightcap can also wreck a good night’s sleep. How could it do both?</p> <p>Here’s what’s going on in your body when you drink alcohol just before bedtime. And if you want to drink at the Christmas party, we have some tips on how to protect your sleep.</p> <h2>What happens to my body when I drink?</h2> <p>Soon after you drink, alcohol enters your bloodstream and travels to your brain.</p> <p><a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.1530-0277.1998.tb03695.x">There</a>, it affects chemical messengers known as neurotransmitters and <a href="https://pubmed.ncbi.nlm.nih.gov/2700603/">slows down communication</a> between nerve cells.</p> <p>Certain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4040959/">regions of the brain</a> are particularly vulnerable to the effects of alcohol. When alcohol interacts with cells in these regions, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6826822/">overall effect</a> leads to those characteristic feelings of relaxation, lowered inhibitions, slurred speech, and may induce feelings of drowsiness and lethargy.</p> <p>Alcohol can also have immediate effects on the heart and circulatory system. Blood vessels widen, resulting in a <a href="https://link.springer.com/article/10.1007/s11906-021-01160-7">drop in blood pressure</a>, which can make you feel dizzy or lightheaded.</p> <h2>What happens soon after a nightcap?</h2> <p>Drinking alcohol before sleeping is like flipping a switch. At first, alcohol has a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6826822/">sedative effect</a> and you will probably feel <a href="https://pubmed.ncbi.nlm.nih.gov/23347102/">more relaxed</a> and <a href="https://www.nature.com/articles/s41598-020-62227-0#:%7E:text=In%20this%20large%2C%20population%20based,sleep%20(cross%20sectional%20analyses).">drift off easily</a>.</p> <p>At this point, you still have a high level of alcohol in your blood. But don’t be fooled. As your body <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5821259/">processes the alcohol</a>, and the night goes on, alcohol actually <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/acer.12621">disrupts your sleep</a>.</p> <h2>And later that night?</h2> <p>As your body processes the alcohol and your blood alcohol level drops, your brain rebounds from the drowsiness you would have felt earlier in the night.</p> <p>This disturbs your sleep, and can wake you up <a href="https://journals.sagepub.com/doi/10.1300/J465v26n01_01">multiple times</a>, particularly in the second half of the night. You may also have vivid and stressful <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5821259/">dreams</a>.</p> <p>This sleep disruption is mainly to the deep, “rapid eye movement” or REM sleep.</p> <p>This type of sleep plays an important role in regulating your emotions and for your cognitive function. So not getting enough explains why you wake up feeling pretty lousy and groggy.</p> <p>Drinking alcohol before bedtime also tends to mean you <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2775419/?source=post_page---------------------------">sleep less overall</a>, meaning important rest and recharge time is cut short.</p> <p>There are also <a href="https://pubmed.ncbi.nlm.nih.gov/31234199/">long-term impacts</a> of alcohol on sleep. Moderate and heavy drinkers consistently have <a href="https://academic.oup.com/sleepadvances/article/3/1/zpac023/6632721">poor sleep quality</a> and more <a href="https://www.nature.com/articles/s41598-020-62227-0#:%7E:text=In%20this%20large%2C%20population%20based,sleep%20(cross%20sectional%20analyses).">sleep disturbances</a> over time.</p> <h2>How about the Christmas party then?</h2> <p>If you plan to drink this holiday season, here are some tips to minimise the effect of alcohol on your sleep:</p> <ul> <li> <p><strong>swap every other drink</strong>. Try swapping every second drink for a non-alcoholic drink. The more alcohol you drink, <a href="https://academic.oup.com/sleep/article/44/1/zsaa135/5871424?casa_token=okbJAuf8TXUAAAAA:ye_q-DACToxvj8H3IVaiKrjNkDhHZnl-LKJdds3iteaKyzJFuHUzitlRv45DqxNO-FraDRAlQMV53z8">the more</a> sleep disruption you can expect. Reducing how much you drink in any one sitting can minimise the effect on your sleep</p> </li> <li> <p><strong>avoid drinking alcohol close to bedtime</strong>. If you give your body a chance to process the alcohol before you go to sleep, your sleep will be less disrupted</p> </li> <li> <p><strong>eat while you drink</strong>. Drinking on an empty stomach is going to worsen the effects of alcohol as the alcohol will be absorbed <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1467-3010.2006.00588.x?casa_token=TQiCqcbasYAAAAAA:GbEvnTT82aB3_sPfmJLOQXIV3ivjnbZdIoP2_XZBa8IDZ0YLaPxNfE6DMHLgH7obnpA22VDsM4vyGZV4dQ">faster</a>. So try to eat something while you’re drinking</p> </li> <li> <p><strong>ditch the espresso martinis and other caffeinated drinks</strong>. <a href="https://www.sciencedirect.com/science/article/pii/S1087079207000937?casa_token=NJsobF-C-vwAAAAA:opzPjrglPdZTwXEo7rHil5vm0a1K3KmXw9vp0Het-eRHZEWbfRAA40vgicU3Z5kC8x7uEJF39C8">Caffeine</a> can make it hard to get to sleep, and hard to stay asleep</p> </li> <li> <p><strong>be careful if you have sleep apnoea</strong>. People who have sleep apnoea (when their upper airway is repeatedly blocked during sleep) can be even more impacted by drinking alcohol. That’s because alcohol can act as a muscle relaxant, <a href="https://academic.oup.com/sleep/article/5/4/318/2753287">leading to</a> more snoring, and lower oxygen levels in the blood. If you have sleep apnoea, limiting how much alcohol you drink is the best way to avoid these effects</p> </li> <li> <p><strong>drink plenty of water</strong>. Staying hydrated will help you <a href="https://academic.oup.com/sleep/article/42/2/zsy210/5155420">sleep better</a> and will hopefully stave off the worst of tomorrow’s hangover.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/216834/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/madeline-sprajcer-1315489">Madeline Sprajcer</a>, Lecturer in Psychology, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>; <a href="https://theconversation.com/profiles/charlotte-gupta-347235">Charlotte Gupta</a>, Postdoctoral research fellow, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>; <a href="https://theconversation.com/profiles/chris-irwin-249481">Chris Irwin</a>, Senior Lecturer in Nutrition and Dietetics, School of Health Sciences &amp; Social Work, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a>; <a href="https://theconversation.com/profiles/grace-vincent-1484516">Grace Vincent</a>, Senior Lecturer, Appleton Institute, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a>, and <a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, Senior Lecturer and Discipline Lead in Nutrition, School of Health, Medical and Applied Sciences, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Drinking alcohol this Christmas and New Year? These medicines really don’t mix

A cool crisp beer at the beach. Some cheeky cocktails with friends to see in the New Year. There seem to be so many occasions to unwind with an alcoholic drink this summer.</p> <p>But if you’re taking certain medications while drinking alcohol, this can affect your body in a number of ways. Drinking alcohol with some medicines means they may not work so well. With others, you risk a life-threatening overdose.</p> <p>Here’s what you need to know if you’re taking medication over summer and plan to drink.</p> <h2>Why is this a big deal?</h2> <p>After you take a medicine, it travels to the stomach. From there, your body shuttles it to the liver where the drug is metabolised and broken down before it goes into your blood stream. Every medicine you take is provided at a dose that takes into account the amount of metabolism that occurs in the liver.</p> <p>When you drink alcohol, this is also broken down in the liver, and it can affect how much of the drug is metabolised.</p> <p>Some medicines are metabolised <em>more</em>, which can mean not enough reaches your blood stream to be effective.</p> <p>Some medicines are metabolised <em>less</em>. This means you get a much higher dose than intended, which could lead to an overdose. The effects of alcohol (such as sleepiness) can act in addition to similar effects of a medicine.</p> <p>Whether or not you will have an interaction, and what interaction you have, depends on many factors. These include the medicine you are taking, the dose, how much alcohol you drink, your age, genes, sex and overall health.</p> <p>Women, older people and people with liver issues are more likely to have a drug interaction with alcohol.</p> <h2>Which medicines don’t mix well with alcohol?</h2> <p>Many medicines interact with alcohol regardless of whether they are prescribed by your doctor or bought over the counter, such as <a href="https://www.drugs.com/article/herbal-supplements-alcohol.html">herbal medicines</a>.</p> <p><strong>1. Medicines + alcohol = drowsiness, coma, death</strong></p> <p>Drinking alcohol and taking a medicine that depresses the <a href="https://adf.org.au/drug-facts/depressants/">central nervous system</a> to reduce arousal and stimulation can have additive effects. Together, these can make you extra drowsy, slow your breathing and heart rate and, in extreme cases, lead to coma and death. These effects are more likely if you use more than one of this type of medicine.</p> <p>Medicines to look out for include those for depression, anxiety, schizophrenia, pain (except <a href="https://www.nps.org.au/australian-prescriber/articles/alcohol-and-paracetamol">paracetamol</a>), sleep disturbances (such as insomnia), allergies, and colds and flu. It’s best not to drink alcohol with these medicines, or to keep your alcohol intake to a minimum.</p> <p><strong>2. Medicines + alcohol = more effects</strong></p> <p>Mixing alcohol with some medicines increases the effect of those medicines.</p> <p>One example is with the sleeping tablet zolpidem, which is <a href="https://www.tga.gov.au/news/product-recalls/zolpidem-stilnox">not to be taken with alcohol</a>. Rare, but serious, side effects are strange behaviour while asleep, such as sleep-eating, sleep-driving or sleep-walking, which are more likely with alcohol.</p> <p><strong>3. Medicines + craft beer or home brew = high blood pressure</strong></p> <p>Some types of medicines only interact with some types of alcohol.</p> <p>Examples include some medicines for depression, such as phenelzine, tranylcypromine and moclobemide, the antibiotic linezolid, the Parkinson’s drug selegiline, and the cancer drug procarbazine.</p> <p>These so-called <a href="https://www.mydr.com.au/medicine/monoamine-oxidase-inhibitors-maois-for-depression/">monoamine oxidase inhibitors</a> <a href="https://www.health.qld.gov.au/__data/assets/pdf_file/0020/145802/oncol_maoi.pdf">only interact with</a> some types of boutique and artisan beers, beers with visible sediment, Belgian, Korean, European and African beers, and home-made beers and wine.</p> <p>These types of alcohol contain high levels of tyramine, a naturally occurring substance usually broken down by your body that doesn’t ordinarily cause any harm.</p> <p>However, monoamine oxidase inhibitors prevent your body from breaking down tyramine. This increases levels in your body and can cause your blood pressure to rise to dangerous levels.</p> <p><strong>4. Medicines + alcohol = effects even after you stop drinking</strong></p> <p>Other medicines interact because they affect the way your body breaks down alcohol.</p> <p>If you drink alcohol while using such medicines you may you feel nauseous, vomit, become flushed in the face and neck, feel breathless or dizzy, your heart may beat faster than usual, or your blood pressure may drop.</p> <p>This can occur even after you stop treatment, then drink alcohol. For example, if you are taking metronidazole you should avoid alcohol both while using the medicine and for at least 24 hours after you stop taking it.</p> <p>An example of where alcohol changes the amount of the medicine or related substances in the body is acitretin. This medication is used to treat skin conditions such as severe psoriasis and to prevent skin cancer in people who have had an organ transplant.</p> <p>When you take acitretin, it changes into another substance – <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent&amp;id=CP-2017-CMI-02034-1&amp;d=20221221172310101">etretinate</a> – before it is removed from your body. Alcohol increases the amount of etretinate in your body.</p> <p>This is especially important as etretinate can cause birth defects. To prevent this, if you are a woman of child-bearing age you should avoid alcohol while using the medicine and for two months after you stop taking it.</p> <h2>Myths about alcohol and medicines</h2> <p><strong>Alcohol and birth control</strong></p> <p>One of the most common myths about medicines and alcohol is that you can’t drink while using <a href="https://youly.com.au/blog/sexual-reproductive-health/does-alcohol-make-the-pill-less-effective/">the contraceptive pill</a>.</p> <p>It is generally safe to use alcohol with the pill as it <a href="https://www.healthline.com/health/womens-health/birth-control-and-alcohol#:%7E:text=There's%20a%20bit%20of%20good,a%20less%20effective%20birth%20control.">doesn’t directly affect</a> how well birth control works.</p> <p>But the pill is most effective when taken at the same time each day. If you’re drinking heavily, you’re more likely to forget to do this the next day.</p> <p>Alcohol can also make some people nauseous and vomit. If you vomit within three hours of taking the pill, it will not work. This increases your risk of pregnancy.</p> <p>Contraceptive pills can also affect your response to alcohol as the hormones they contain can change the way your body <a href="https://americanaddictioncenters.org/alcoholism-treatment/birth-control">removes alcohol</a>. This means you can get drunk faster, and stay drunk for longer, than you normally would.</p> <p><strong>Alcohol and antibiotics</strong></p> <p>Then there’s the myth about not mixing alcohol with any <a href="https://theconversation.com/mondays-medical-myth-you-cant-mix-antibiotics-with-alcohol-4407">antibiotics</a>. This only applies to <a href="https://www.healthdirect.gov.au/medicines/medicinal-product/aht,21161/metronidazole">metronidazole</a> and <a href="https://www.healthdirect.gov.au/medicines/brand/amt,1011571000168100/linezolid-apo">linezolid</a>.</p> <p>Otherwise, it is generally safe to use alcohol with antibiotics, as alcohol does not affect how well they work.</p> <p>But if you can, it is best to avoid alcohol while taking antibiotics. Antibiotics and alcohol have similar side effects, such as an upset stomach, dizziness and drowsiness. Using the two together means you are more likely to have these side effects. Alcohol can also reduce your energy and increase how long it takes for you to recover.</p> <h2>Where can I go for advice?</h2> <p>If you plan on drinking alcohol these holidays and are concerned about any interaction with your medicines, don’t just stop taking your medicines.</p> <p>Your pharmacist can advise you on whether it is safe for you to drink based on the medicines you are taking, and if not, provide advice on alternatives.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/196646/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/nial-wheate-96839"><em>Nial Wheate</em></a><em>, Associate Professor of the Sydney Pharmacy School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/jessica-pace-1401278">Jessica Pace</a>, Associate Lecturer, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

No gavels, no hearsay and lots of drinking: a law expert ranks legal dramas by their accuracy

<p><em><a href="https://theconversation.com/profiles/dale-mitchell-1468293">Dale Mitchell</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a></em></p> <p>From Elle Woods in Legally Blonde to <a href="https://www.tandfonline.com/doi/abs/10.1080/10383441.2015.1087367">Jennifer Walters in She-Hulk</a>, Atticus Finch in To Kill a Mockingbird to Denny Crane in Boston Legal, our popular culture is often where we first see and witness legal practice.</p> <p>Sometimes this comes via the silver screen, other times television. But it would be wrong to think that all we see on legal television shows is accurate – even when it claims to capture reality.</p> <p>Most legal dramas are terrible at capturing the realities of law.</p> <h2>Not accurate: Law(less) and (dis)Order</h2> <p>Law and Order (1990-) innovated television drama by showcasing both the investigation of a crime by police, and then its prosecution in court. With its multiple spin-offs, including Law and Order: Special Victims Unit (1999-) and the shortlived Law and Order: Trial by Jury (2005-2006) (which had the <a href="https://www.youtube.com/watch?v=aolG65V1Dx8">best theme song of all the series</a>), the Law and Order franchise is a televisual legal juggernaut.</p> <figure><iframe src="https://www.youtube.com/embed/aolG65V1Dx8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>As with most serials, Law and Order presents the criminal justice system as moving quicker than you can say <em>dun dun</em>. This couldn’t be further from the truth. The mean duration of criminal law matters in Australian higher courts was <a href="https://www.abs.gov.au/statistics/people/crime-and-justice/criminal-courts-australia/latest-release">almost one year</a> (50 weeks) across 2021-22.</p> <p>While <a href="http://classic.austlii.edu.au/au/legis/qld/consol_reg/ucpr1999305/s5.html">procedural rules in civil matters</a> require courts to facilitate the “just and efficient resolution of disputes at minimum expense”, in criminal law, speed and efficiency must not be prioritised over accuracy: a person’s liberty is at stake.</p> <p>Most criminal matters do not proceed to a full trial as an accused will often plead guilty to the charges. As a result, the matter proceeds to sentencing without prosecutors needing to prove the offence. The rates of this occurring are quite alarming. <a href="https://www.abs.gov.au/statistics/people/crime-and-justice/criminal-courts-australia/latest-release">Data across 2021-22</a> reveals over 75% of defendants in Australian courts entered a guilty plea, and almost four in five criminal convictions (79%) resulted from a guilty plea.</p> <p><a href="https://law.unimelb.edu.au/__data/assets/pdf_file/0009/1705761/32_1_8.pdf">Research suggests</a> defendants plead guilty for a variety of reasons, including to avoid the cost of a trial and to receive a lesser sentence. <a href="https://theconversation.com/pandemic-pushed-defendants-to-plead-guilty-more-often-including-innocent-people-pleading-to-crimes-they-didnt-commit-165056">Data from the United States</a> suggests the pressures of the pandemic led to innocent people pleading guilty to crimes they didn’t commit.</p> <p>If Law and Order was a more accurate reflection of criminal law, matters would proceed immediately to sentencing due to guilty pleas. And should an accused be found guilty, a chunk of their sentence would be reduced by time served awaiting trial.</p> <figure><iframe src="https://www.youtube.com/embed/60GV5lv8h3o?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Not accurate: Suits</h2> <p>Suits (2011-19) centres around law firm partner Harvey Specter (Gabriel Macht) and his mentorship of Mike Ross (Patrick Adams) – the “lawyer” who never graduated law school and provides legal advice thanks to his photographic memory.</p> <p>This is, obviously, a brutal ethical breach for all involved, and clearly fraud. In Australia, law students who present themselves to be lawyers are <a href="https://www.abc.net.au/news/2016-09-07/law-graduate-jacob-reichman-fined-posing-solicitor-gold-coast/7824324">subject to sanctions</a> by the Legal Services Commission. They can <a href="https://www.lawyersweekly.com.au/biglaw/35821-fake-lawyer-cops-suspended-jail-sentence">cause harm to clients</a> who have hired their services. And the Legal Admissions Board may <a href="https://www.qlsproctor.com.au/2020/11/chief-justice-wants-answers-before-considering-lawyer-impersonators-bid-to-become-legal-practitioner/">deny their entry</a> into the profession.</p> <p>(Spoilers) Ross is eventually sentenced to two years in prison for this fraud, a similar sentence to <a href="https://www.law.com/thelegalintelligencer/almID/1202786675709/">a recent case in the United States</a>, but he only serves three months before solving a crime and earning early release. More unrealistic than this early release is that Ross does fairly quickly thereafter gain admission to the profession, which seems unlikely to occur so soon after such an act of fraud.</p> <p>While Suits has left its mark(le) on the popular imagination of law, it fails to address one of the primary duties of civil litigation: the duty of disclosure.</p> <p>The MacGuffin-ing of law is common in TV serials. It’s the “smoking gun” found on the day of the trial, or for the lawyers in Suits, the random document which shows up <em>during</em> the trial to turn the case - dramatically presented by our protagonists as they flail into court armed with this data sans ethics.</p> <p>This is not quite accurate.</p> <p>In adversarial legal systems like Australia, New Zealand, the UK and the US, civil litigation rules <a href="http://classic.austlii.edu.au/au/legis/qld/consol_reg/ucpr1999305/s211.html">require parties</a> to disclose to one another all documents in their possession or control which are directly relevant to a matter in dispute.</p> <p>This is a continuing duty, so if you discover such a document at any time during the case, it must be disclosed. While <a href="http://classic.austlii.edu.au/au/legis/qld/consol_reg/ucpr1999305/s212.html">exceptions</a> based on various privileges may apply, this essentially means civil litigation must be run in an “all cards on the table” manner. Randomly producing undisclosed material at trial requires the leave of the court and may result in orders of contempt and <a href="http://classic.austlii.edu.au/au/legis/qld/consol_reg/ucpr1999305/s225.html">cost penalties</a>.</p> <p>It’s not like the lawyers of Suits have ever really been concerned about ethics, though.</p> <figure><iframe src="https://www.youtube.com/embed/wUh9jomHZp4?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Not accurate: How to Get Away with Murder(ing rules of evidence)</h2> <p>While most lawyers would support making it a criminal offence to critique Viola Davis, How to Get Away with Murder (2014-20) presents one of the most common offences within legal dramas: the haphazard approach to rules of evidence.</p> <p>Annalise Keating (Davis) and her ragtag team of morally illiterate law students (although I never see them studying?!?!) manipulate people to obtain evidence and then dramatically prompt witnesses on the stand to read this information into the record, or otherwise “sneak” it into the trial.</p> <p>This is not accurate. And it ignores the basic reality that so much of legal practice is about not just obtaining evidence, but ensuring that evidence is admissible in court.</p> <p>One of the most important rules of evidence deals with <a href="http://classic.austlii.edu.au/au/legis/cth/consol_act/ea199580/s59.html"><em>hearsay evidence</em></a>. A court cannot allow evidence to be considered if its reliability is unable to be interrogated. Witnesses can only present evidence that they saw, heard or perceived themselves. Unless an exception to the hearsay rule applies, such evidence would be inadmissible.</p> <p>Like in Suits, these approaches to presenting evidence may have serious implications. This poor trial management results in <a href="https://www.aic.gov.au/sites/default/files/2020-05/rpp074.pdf">delays to criminal trials.</a>.</p> <figure><iframe src="https://www.youtube.com/embed/rMB_Gw5-T-I?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Accurate: Fisk</h2> <p>Fisk (2021-) follows Helen Tudor-Fisk (Kitty Flanagan), an established contract lawyer whose personal dramas lead her to move to the boutique Melbourne probate law firm of Gruber and Gruber (played by Marty Sheargold and Julia Zamero).</p> <p>Fisk excels in showing the importance of lawyer-client relations and the word-of-mouth that sustains much of small legal practice. It’s the anti-Suits, and Fisk is more powerful for it.</p> <p>The discussions of wills and estates and most basic legal principles in Fisk are mostly sound – and the show doesn’t need to get into “legalese” as matters are resolved out-of-court.</p> <p>This is a distinct reality of law: litigation is a last resort. Forms of <a href="https://www.qls.com.au/Practising-law-in-Qld/ADR/Alternative-Dispute-Resolution/Types-of-Alternative-Dispute-Resolution-(ADR)">alternative dispute resolution</a>, including mediation, negotiation and conciliation, have become the primary way of resolving legal disputes.</p> <p>Fuelled by <a href="https://www.ag.gov.au/legal-system/alternative-dispute-resolution/civil-dispute-resolution-act-2011">legislative changes</a> which require the exhaustion of alternative dispute resolution measures before proceeding to litigation, and a pursuit of reduced costs, the drama of trial is not something anyone should yearn for.</p> <figure><iframe src="https://www.youtube.com/embed/N1Qt0Wo1gGo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Accurate: Rake</h2> <p>Cleaver Greene, a character said to be loosely based on the career of a Sydney barrister, shows us the absolute madness of work as a “<a href="https://nswbar.asn.au/the-bar-association/senior-counsel#:%7E:text=Senior%20counsel%20are%20barristers%20who,a%20QC%20or%20queen's%20counsel.">silk</a>”. Rake excels at showing the reality of law. The show raises interesting and accurate questions of law (yes, it is true there is no <a href="https://opus.lib.uts.edu.au/bitstream/10453/18992/1/2011006119.pdf">explicit offence</a> of cannibalism in New South Wales) and presents Australian court process accurately.</p> <p>Thankfully, there’s not a gavel in sight. <a href="https://www.survivelaw.com/post/941-working-hardly-random-facts-about-the-gavel">Australian courts <em>do not</em> use gavels</a>, and their presence in legal dramas in Australian and UK courts shows a lack of attention to detail. The presence of the gavel as a symbol of justice is <a href="http://www5.austlii.edu.au/au/journals/NSWBarAssocNews/1994/17.pdf">an entirely American invention</a>.</p> <figure><iframe src="https://www.youtube.com/embed/qWWI2EdOssk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Rake is accurate, in part, because the site of drama is rarely the courtroom, but rather Greene’s personal life.

These 8 food and drink favourites are bad for your brain

<p><strong>Bad foods for your brain</strong></p> <p>Following a healthy diet is essential to maintaining optimal brain health. Avocados and fatty fish; bone broth, berries and broccoli – they’re all brain-boosting superstars. But there are plenty of foods that have the opposite effect and can sap your smarts, affecting your memory and mood. Therefore, it’s important to cut or reduce the following food from your diet to mitigate their effects.</p> <p><strong>Fried foods</strong></p> <p>Fried chicken and French fries won’t just widen your waistline, they are also bad for your brain. In a study published in 2016 in the Journal of Nutritional Science, people who ate diets high in fried foods scored poorly on cognitive tests that evaluated learning, memory and brain function. Conversely, those who ate more plant-based foods scored higher.</p> <p>“Scientists think it may have something to do with inflammation and reduction in brain tissue size,” says Kristin Kirkpatrick, co-author of Skinny Liver. “When you look at aspects of one of the great brain studies – the MIND diet – it clearly shows which foods may cause or reduce inflammation in the brain. Fried foods are on the NO list, while berries, olive oil, whole grains and food containing omega 3 are on the YES list.”</p> <p><strong>Sugar-sweetened beverages</strong></p> <p>You probably know to stay away from soft drinks. But you should also beware of fruit juice, energy drinks and sweet tea. Why, you ask? The same reason soft drink is among the bad foods for your brain: sugar.</p> <p>“High amounts of sugar causes neurological damage” because it triggers inflammation, says the Academy of Nutrition and Dietetics’ Wesley Delbridge. A study published in 2017 in Alzheimer’s &amp; Dementia backs that up. Researchers found that people who regularly consume sugary drinks are more likely to have poorer memory, smaller overall brain volume, and a significantly smaller hippocampus – the part of the brain important for learning and memory – than those who don’t.</p> <p>Instead of drinking fruit juice or sweet tea high in sugar, try sweetening water or tea with slices of oranges, lemons, or limes.</p> <p><strong>Refined carbs</strong></p> <p>White rice, white bread, white pasta and other processed food with a high glycemic index don’t just cause major spikes in blood sugar, they also rank with the ‘bad foods for your brain’. Specifically, these foods can have a negative effect on your mental health. A study, published in 2015 in The American Journal of Clinical Nutrition found that food with a high glycemic index can raise the risk of depression in post-menopausal women. Women who ate more lactose, fibre, fruit and vegetables, on the other hand, showed a significant decrease in symptoms of depression.</p> <p>Swap the white carbs for complex carbs like whole wheat bread, brown rice, quinoa, barley, and farro. All of these contain fibre, which nurtures your gut bacteria and regulates inflammation – all good things for your brain health.</p> <p><strong>Excess alcohol</strong></p> <p>There is a sweet spot for alcohol consumption, according to neurologist Dr David Perlmutter and author of Grain Brain: The Surprising Truth about Wheat, Carbs, and Sugar. While the occasional glass of red wine is okay, drinking in excess can be toxic to your brain function, no matter your age. Research, including a study published in 2017 in the peer-reviewed medical trade journal BMJ, found that moderate drinking can damage the brain. The hippocampus is particularly vulnerable.</p> <p>To protect your brain, limit alcohol consumption to no more than one standard drink per day for women and two per day for men. According to Australia’s national alcohol guidelines, one standard drink is defined as containing 10 grams of alcohol. </p> <p><strong>Artificially sweetened beverages</strong></p> <p>Instead of a sugar-sweetened beverage, maybe you turn to the occasional diet soft drink. But make a habit of it and you could be upping your risk of dementia and stroke, suggests a study published in 2017 in Stroke. Researchers found that participants who drank diet drinks daily were almost three times as likely to have a stroke or develop dementia when compared to those who didn’t.</p> <p>“We seek out diet soft drinks for its sweet delivery of liquid,” says Kirkpatrick. “That sweet taste remains on our taste buds, making us crave more.”</p> <p>To kick the habit, she suggests going cold turkey. “Eliminate all sources of sweet from the taste buds to retrain the brain not to want it in the first place,” she says. “Sprucing up water with lemons, limes or berries, or having flavoured seltzer without added sugar can help, as well.”</p> <p><strong>Processed meats </strong></p> <p>If you like to eat processed meats, you may run a greater risk of developing dementia, suggests an April 2020 study published in Neurology. Although the study does not prove cause and effect, the researchers found that dementia was more common among participants who ate highly processed meats, such as sausages, cured meats and pâté. People without dementia were more likely to eat a diverse diet that included fruit, vegetables, seafood and poultry, according to the findings.</p> <p>Highly processed foods are most likely the primary cause of results linked to the reduction in brain tissue size and inflammation, which impacts brain health, says Kirkpatrick.</p> <p><strong>Fast food </strong></p> <p>For starters, the high levels of saturated fat found in greasy burgers and fries can make it harder to fight off Alzheimer-causing plaque. Plus, the level of sodium found in the average fast-food fix can cause brain fog. How so?  High blood pressure, often brought on by eating too many salty foods, can restrict blood to the brain and negatively impair focus, organisational skills and memory, suggests a review of studies published in 2016 in Hypertension.</p> <p>To break a fast food habit, Kirkpatrick suggests this trick: “Start with altering what you order,” she says. “Avoid fried options and opt for more whole grains and plants.” Then reduce the number of days you buy fast food by half.</p> <p><strong>Tuna</strong></p> <p>While the occasional tuna sandwich is no big deal, you might want to think twice before making it your go-to lunch. That’s because tuna – as well as swordfish, shark (flake), bill fish and deep sea perch – has higher levels of mercury than many other types of seafood. A study published in Integrative Medicine shows that people with high levels of the heavy metal in their bloodstream had a 5% drop in cognitive function.</p> <p>But you don’t have to banish seafood from your plate forever. Advice from Food Standards Australia New Zealand (which reflects the fish we eat in our region and its mercury content) recommends 2-3 serves per week of fish and seafood, including canned or fresh tuna (one serve equals 150g), except for fish such as orange roughy (deep sea perch), catfish, shark (flake) or billfish (swordfish/marlin), which you should only consume 1 serve per week and no other fish that week.</p> <p>Try swapping these varieties of fish for omega-3-rich sources such as wild salmon and lake trout, which have been associated with better brain health, says Kirkpatrick.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/the-8-worst-foods-for-your-brain" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

10 driving tips to stay safe in wet weather

<p><strong>Driving in the rain? Follow these tips for safe driving in wet weather </strong></p> <p>This should go without saying, but reducing your speed – as long as you continue to keep with the flow of traffic, of course – is imperative when driving in the rain. </p> <p>After all, between the downpour and spray from other vehicles, heavy rain reduces visibility in all directions, and you need more time to react.</p> <p><strong>Keep your distance </strong></p> <p>Driving in the rain can be hazardous, and if ever there is an incident that requires you – or the driver in front you – to brake unexpectedly, you’ll want to have ample stopping distance on wet roads.</p> <p><strong>Avoid heavy breaking </strong></p> <p>While driving in the rain, you may find yourself in situations – whether you’re hydroplaning or finding yourself in a skid – that will tempt you to hit the brakes abruptly. Do your best to curb that impulse. </p> <p>Brakes can be affected greatly by water, losing a bit of their power when wet, which can be disastrous in an emergency. Easing off the brakes, slowing down and maintaining control of your vehicle is your best bet.</p> <p><strong>Keep both hands on the wheel </strong></p> <p>Control is of utmost importance when driving in the rain. After all, you need to be in command of your vehicle should an incident occur, and having both hands on the wheel while driving in the rain (no snacking or fiddling with the radio!) will ensure you can get out of a sticky situation quickly and efficiently.</p> <p><strong>Keep windows from fogging up</strong></p> <p>When driving in rain, windows tend to fog up as a result of the difference in temperatures inside and outside the car and can lead to decreased visibility. To stay safe and avoid accidents, simply press your car’s defrost button to clear-up the window. </p> <p>Turn on your A/C or roll down the windows by a couple of centimetres to remove the humidity from the vehicle and lower the temperature inside the car. If the issue persists, you may want to purchase a windshield cleaner and defogger.</p> <p><strong>Beware of hydroplaning </strong></p> <p>Hydroplaning happens when your car travels above the water without touching the ground. Given that a driver is left with little-to-no grip with the road and, thus, less control, this can be a dangerous set of circumstances. If you find yourself in such a situation, stay calm, ease off the brakes and do not turn your steering wheel; let your car slow down and the tires reattach to the road surface.</p> <p><strong>Avoid puddles</strong></p> <p>Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain.</p> <p><strong>Stay home if you can </strong></p> <p>If you have no choice but to head outside during a heavy downpour, be sure to follow these driving tips. However, if you don’t have anywhere pressing to be, consider staying home and waiting it out until the storm subsides.</p> <p><strong>Keep your headlights on</strong></p> <p>With wet weather often comes fog and overall gloominess. With your surroundings slightly darkened, turning on your headlights ensures that you can see the road in front of you, and that other drivers can see you.</p> <p><strong>Ensure windshield wipers are in working order</strong></p> <p>Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/home-tips/10-driving-tips-to-stay-safe-in-wet-weather" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

A drink each day or just on the weekends? Here’s why alcohol-free days are important

Does artificial sweetener aspartame really cause cancer? What the WHO listing means for your diet soft drink habit

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>The International Agency for Research on Cancer (IARC), which is the specialised cancer agency of the World Health Organization, has declared aspartame may be a <a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possible carcinogenic hazard to humans</a>.</p> <p>Another branch of the WHO, the Joint WHO and Food and Agriculture Organization’s Expert Committee on Food Additives has assessed the risk and developed recommendations on how much aspartame is safe to consume. They have recommended the acceptable daily intake be 0 to 40mg per kilo of body weight, as we currently have <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">in Australia</a>.</p> <p>A hazard is different to a risk. The hazard rating means it’s an agent that is capable of causing cancer; a risk measures the likelihood it could cause cancer.</p> <p>So what does this hazard assessment mean for you?</p> <h2>Firstly, what is aspartame?</h2> <p><a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">Aspartame is an artificial sweetener</a> that is 200 times sweeter than sugar, but without any kilojoules.</p> <p>It’s used in a <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">variety of products</a> including carbonated drinks such as Coke Zero, Diet Coke, Pepsi Max and some home brand offerings. You can identify aspartame in drinks and foods by looking for additive number 951.</p> <p>Food products such as yogurt and confectionery may also contain aspartame, but it’s not stable at warm temperatures and thus not used in baked goods.</p> <p>Commercial names of aspartame include Equal, Nutrasweet, Canderel and Sugar Twin. In Australia the acceptable daily intake is 40mg per kilo of body weight per day, which is about 60 sachets.</p> <p><a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food#:%7E:text=How%20many%20packets%20can%20a,based%20on%20its%20sweetness%20intensity%3F&amp;text=Notes%20About%20the%20Chart%3A,50%20mg%2Fkg%20bw%2Fd">In America</a> the acceptable daily intake has been set at 75 sachets.</p> <h2>What evidence have they used to come to this conclusion?</h2> <p><a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">IARC looked closely</a> at the <a href="https://cdn.who.int/media/docs/default-source/nutrition-and-food-safety/july-13-final-summary-of-findings-aspartame.pdf?sfvrsn=a531e2c1_5&amp;download=true">evidence base</a> from around the world – using data from observational studies, experimental studies and animal studies.</p> <p>They found there was some limited evidence in human studies linking aspartame and cancer (specifically liver cancer) and limited evidence from animal studies as well.</p> <p>They also considered the biological mechanism studies which showed how cancer may develop from the consumption of aspartame. Usually these are lab-based studies which show exactly how exposure to the agent may lead to a cancer. In this case they found there was limited evidence for how aspartame might cause cancer.</p> <p>There were only three human studies that looked at cancer and aspartame intake. These large observational studies used the intake of soft drinks as an indicator of aspartame intake.</p> <p>All three found a positive association between artificially sweetened beverages and liver cancer in either all of the population they were studying or sub-groups within them. But these studies could not rule out other factors that may have been responsible for the findings.</p> <p>A study <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6284800/">conducted in Europe</a> followed 475,000 people for 11 years and found that each additional serve of diet soft drink consumed per week was linked to a 6% increased risk of liver cancer. However the scientists did conclude that due to the rarity of liver cancer they still had small numbers of people in the study.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/35728406/">In a study from the US</a>, increased risk of liver cancer was seen in people with diabetes who drank more than two or more cans of a diet soda a week.</p> <p>The <a href="https://aacrjournals.org/cebp/article/31/10/1907/709398/Sugar-and-Artificially-Sweetened-Beverages-and">third study</a>, also from the US, found an increase in liver cancer risk in men who never smoked and drank two or more artificially sweetened drinks a day.</p> <p>From this they have decided to declare aspartame as a Group 2b “possible carcinogen”. But they have also said more and better research is needed to further understand the relationship between aspartame and cancer.</p> <p>IARC has four categories (groupings) available for potential substances (or as they are referred to by IARC, “agents”) that may cause cancer.</p> <h2>What does each grouping mean?</h2> <p><strong>Group 1 Carcinogenic to humans:</strong> an agent in this group is carcinogenic, which means there is convincing evidence from human studies and we know precisely <em>how</em> it causes cancer. There are 126 agents in this group, including tobacco smoking, alcohol, processed meat, radiation and ionising radiation.</p> <p><strong>Group 2a Probably carcinogenic to humans:</strong> there are positive associations between the agent and cancer in humans, but there may still be other explanations for the association which were not fully examined in the studies. There are 95 agents in this group, including red meat, DDT insecticide and night shift work.</p> <p><strong>Group 2b Possibly carcinogenic in humans:</strong> this means limited evidence of causing cancer in humans, but sufficient evidence from animal studies, or the mechanism of how the agent may be carcinogenic is well understood. This basically means the current evidence indicates an agent may possibly be carcinogenic, but more scientific evidence from better conducted studies is needed. There are now <a href="https://monographs.iarc.who.int/agents-classified-by-the-iarc/">323</a> agents in this group, including aloe vera (whole leaf extract), ginkgo biloba and lead.</p> <p><strong>Group 3 Not classifiable as a carcinogen:</strong> there’s not enough evidence from humans or animals, and there is limited mechanistic evidence of how it may be a carcinogen. There are 500 agents in this group.</p> <h2>So do I have to give up my diet soft drink habit?</h2> <p>For a 70kg person you would need to consume about 14 cans (over 5 litres) of soft drink sweetened with aspartame a day to reach the acceptable daily intake.</p> <p>But we need to remember there may also be aspartame added in other foods consumed. So this is an unrealistic amount to consume, but not impossible.</p> <p>We also need to consider all the evidence on aspartame together. The foods we typically see aspartame in are processed or ultra-processed, which have recently also been <a href="https://theconversation.com/ultra-processed-foods-are-trashing-our-health-and-the-planet-180115">shown to be detrimental to health</a>.</p> <p>And artificial sweeteners (including aspartame) <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892765/#!po=59.3750">can make people crave more sugar</a>, making them want to eat more food, potentially causing them to gain more weight.</p> <p>All together, this indicates we should be more careful about the amount of artificial sweeteners we consume, since they <a href="https://theconversation.com/the-who-says-we-shouldnt-bother-with-artificial-sweeteners-for-weight-loss-or-health-is-sugar-better-205827">do not provide any health benefits</a>, and have possible adverse effects.</p> <p>But overall, from this evidence, drinking the occasional or even daily can of a diet drink is safe and probably not a cancer risk.</p> <hr /> <p><em>Correction: this article originally stated each serve of soft drink in a study was linked to a 6% increased risk of liver cancer, however it was each additional serve per week.

5 money mistakes that drive experts crazy and what to do instead

<p>Cost of living has hit us hard across the board, from interest rate rises through to inflation increasing the price of a weekly shop along with a range of goods and services. As a financial planner, I spend a lot of my time talking to clients about how to get the most value from their earnings. No matter the income level, there’s often key money mistakes people make that can have a real impact on their financial life in addition to the cost of living pressures. In good news, these can easily be fixed once you start paying attention to them. Let’s take a look at the 5 most common and how to solve them.</p> <p><strong>Thinking too short term</strong></p> <p>People generally spend more time on planning their holidays than to planning their financial lives. It's easy to fall into the trap of thinking to short-term. If we get paid weekly or fortnightly or monthly we tend to think about planning and spending in the same timeframe. There is real benefit though too having some medium and long term planning. Medium term planning is especially important for paying off debts and savings goals. Long term planning is especially important for your retirement planning including your superannuation and even paying off a home loan. </p> <p>So spend some time thinking about your medium and long term goals too. The average weekly wage in Australia is $1,769.80 per week.  Over 12 months that is $92,029.60. Over a 45 year working life that amount is over $4.1 million. That’s a lot of income! Respect your earnings and make a plan to make the most of it, not only in the short term, but the medium and long term too. </p> <p><strong>Not paying attention to your spending</strong></p> <p>As a financial planner I’ve genuinely lost count of the number of clients I’ve had sitting across the desk from me who earn great money but don't know where a great deal if it goes. They earn a good wage and they have a sense that things are going OK, because they think too short term. They also don’t pay attention to their spending. As a result they miss out on medium and long-term opportunities to make the most of their earnings. Paying attention to your spending doesn't mean that you have to give up the things you love for example a morning coffee on your way to work either. </p> <p>Paying attention to your spending is not like being on a diet. It’s not about going without. It’s about making sure when you do spend your hard earned money you shop around to try and get the best value you can. Credit cards, loans, car insurance, mobile phones, electricity bills and health insurance are all regular expenses most people have. They should however never be set and forget. Find better value and pay attention to your spending. It will give you the opportunity to save and invest more and achieve your goals sooner.</p> <p><strong>Being uninterested in interest rates</strong></p> <p>Ask anyone with a home loan right now and they will tell you about the impact of rising interest rates on their life. Interest is the cost of money. If you’re a lender, it’s what you pay for borrowing money. It might be a short-term loan like a credit card, a medium-term loan like a personal loan for a car, or a long-term loan to help you buy a mortgage. If you’re an investor interest also matters. Let’s say you’ve saved $50,000 and were getting a 4% return, that’s an extra $2,000 a year on top of your current wage or salary. I’m sure there’s lots you could do with that money.</p> <p>Regardless if you’re a borrower or an investor, the interest rate you’re paying or earning matters. Over time, interest adds up. Over 5 years, for example, that $2,000 becomes $10,000, plus there’s interest earned on the interest too. If you’ve got debt pay it back as quickly as you can comfortably afford to. And if you’re about to get a debt, factor in a few additional interest rate rises. It is really important to make sure you stress-test your ability to pay back the loan under higher interest rates. </p> <p><strong>Not keeping it real</strong></p> <p>Most things we do in life have a financial consequence and it’s important to keep it real. I spend a great of my time as a financial planner asking people what really matters to them. Is life really about showing off to family and friends new purchases on Instagram? Probably not. Having a focus on your own goals makes a world of difference. It provides you with something that can drive you forward. One of the real dangers of the social media world we live in today, especially for younger Australians is the desire to keep up with their friends. What they often don’t see is the financial stress their friends are putting themselves under to have everything right now or the difficult conversations behind closed doors about how to keep it going or reduce the financial stress they’re not telling you about.</p> <p>Your only obligation in your adult financial life is to yourself, your spouse and your kids if you have them. Being overconfident is just as dangerous for your financial health as being too under confident in your financial life. Being overconfident may make you take too much risk. Being too conservative might mean you miss out on opportunities. At the end of the day you need to find the right balance for you and make sure the goals you set and the financial decisions you make are within your own comfort zone. </p> <p><strong>Forgetting to reward and celebrate success along the way</strong></p> <p>If you’re going to set yourself some medium and long-term goals, pay attention to your spending and interest rates as well as keeping it real, then you also need to reward yourself along the way. Rewarding yourself for achieving goals makes setting goals much easier. And if you’ve got medium and long term goals like paying off a car loan, paying down the mortgage or saving into super for your retirement, celebrate key milestones. For example it might be going out for a nice dinner or getting concert tickets for every $25,000 that’s saved into super or paid off a home loan.</p> <p>Your financial life done well shouldn’t be a chore or a bore. If it is you’re doing it wrong. Spend some time and energy to rethink your financial life, learn more about how money works and go forward more confidently to achieve your goals. </p> <p><strong><em>Luke Smith is a licensed Australian financial planner and author of the new book, Smart Money Strategy – Your Ultimate Guide to Financial Planning (Wiley, $34.95), published by Wiley.

The best and worst drinks for people with diabetes

<p><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;">Choosing the right drinks for people with diabetes is as important as choosing the right foods, and it isn’t always simple. Is coffee helpful or harmful to insulin resistance? Does zero-calorie diet soda affect your blood sugar? Some studies may only add to the confusion. We reviewed the research and then asked three top registered dietitians, who are also certified diabetes educators, what they tell their clients about seven everyday drinks for people with diabetes. Here’s what to know before you sip.</span></p> <h4><span style="color: #444444; font-family: Raleway, sans-serif, Helvetica Neue, Helvetica, Arial;">Drink more: Water</span></h4> <p>Drinking enough water has so many health benefits. But could downing a few glasses of H2O help control your blood sugar? A study in the journal Diabetes Care suggests so: The researchers found that people who drank 475ml (two cups’ worth) or less of water a day were about 30 percent more likely to have high blood sugar than those who drank more than that daily. The connection seems to be a hormone called vasopressin, which helps the body regulate hydration. Vasopressin levels increase when a person is dehydrated, which prompts the liver to produce more blood sugar.</p> <p><strong>How much:</strong> Experts recommend six to nine 250ml glasses of water per day for women and slightly more for men. You’ll get some of this precious fluid from fruit and vegetables and other fluids, but not all of it. “If you’re not in the water habit, have a glass before each meal,” recommends registered dietitian Constance Brown-Riggs, a certified diabetes educator. “After a few weeks, add a glass at meals too.” If you’re already meeting your water targets, there’s no need to push it further.</p> <h4>Drink more: Milk</h4> <p>Moo juice isn’t just a kids’ drink – it’s one of the best drinks for people with diabetes, too. It provides the calcium, magnesium, potassium and vitamin D your body needs for many essential functions. “Low-fat or fat-free milk is a great beverage for people with diabetes,” Brown-Riggs says. Drinking more milk can also help prevent strokes (a concern for many people with diabetes) by 7 percent, according to research from the <em>Journal of the American Heart Association</em>. Bonus: The researchers also found that eating cheese produced the same effect. If you’re lactose intolerant or allergic to dairy, eating plenty of dark green vegetables can help you obtain the calcium and other electrolytes you need.</p> <p><strong>How much: </strong>Experts recommend eating two to three daily servings of dairy products, including low-fat or fat-free milk. Milk does contain carbohydrates so remember to factor in 12 grams of carbohydrate for every 250ml glass. “Drink milk with a meal so your body can handle the natural rise in blood sugar that happens when we eat carbohydrates,” says registered dietitian Angela Ginn, a certified diabetes educator.</p> <h4>Drink more: Tea</h4> <p>No kilojoules, big flavour, and a boatload of antioxidants have made tea – particularly green and black – trendy for health reasons, especially when it comes to drinks for people with diabetes. Sipping more than three cups of tea a day could lower the risk for developing diabetes, other researchers found. Tea may also help reduce your risk of stroke and heart disease. The exception to these diabetic drinks: sweetened, bottled iced teas, which have tons of added sugar.</p> <p><strong>How much:</strong> Three to four cups of tea are OK for most people; just be sure the caffeine doesn’t keep you awake at night. More is fine if you opt for decaf. And watch what you add: Avoid sugar and full-fat milk and cream.</p> <h4>Drink carefully: Coffee</h4> <p>A 2018 systematic review and meta-analysis in Nutrition Reviews found that coffee drinkers are at lower risk for developing type 2 diabetes. (A compound in coffee called chlorogenic acid seems to slow absorption of glucose into the bloodstream.) But other research indicates that for people who already have diabetes, coffee may raise blood sugar or make the body work harder to process it. Bottom line: It comes down to how coffee affects your individual blood sugar. What many people with diabetes add to their coffee may be the real issue. “Sugar, sweetened creamers, and high-fat milk and half-and-half can raise your blood sugar and your weight,” Brown-Riggs says.</p> <p><strong>How much:</strong> Experts say sipping two to three cups a day is probably fine, but if you’re having a tough time controlling your blood sugar, it may be worth cutting out coffee to see if it makes a difference. “Everyone’s blood sugar response to foods is unique and individual,” Ginn says.</p> <h4>Drink carefully: Diet soft drink</h4> <p>Are fizzy, zero-calorie drinks a brilliant choice for people concerned about diabetes, or could they do more harm than good? One 2018 study in Current Developments in Nutrition looked at over 2,000 people and found that those who drank diet soft drink every day increased their chances of developing diabetes, leading researchers to conclude that diet soda itself could be a risk factor. The news may be even worse for diabetics drinking zero-calorie sodas. Researchers in Australia looked at 600 patients with diabetes and found that drinking more than four cans of diet soft drink a week doubled their chances of developing proliferative diabetic retinopathy, an eye disease that’s a complication of diabetes.</p> <p><strong>How much:</strong> If you have a soft drink habit, it’s probably OK to sip one zero-calorie drink a day instead of a sugary version, but given the research, it’s best to wean yourself off. Make sure to also drink healthy drinks for people with diabetes like water and tea. Resist the temptation to see diet soft drink as a “magic eraser” allowing you to indulge in foods like chips, dips, sweets, fries, and burgers. People who enjoyed their diet soft drink as part of a healthy diet had lower risk of high blood sugar and high cholesterol than those who ate fried and sugary foods in one study in the <em>American Journal of Clinical Nutrition.</em></p> <h4><span style="color: #444444; font-family: Raleway, sans-serif, Helvetica Neue, Helvetica, Arial;">Drink less: Soft drink and sugary drinks</span></h4> <p>With upwards of 10 teaspoons of sugar in every 375ml can or bottle, sweet drinks can send your blood sugar soaring – and boost your risk for weight gain, high blood pressure, stroke and heart disease. One sugary drink a day can add 630 empty kilojoules and about 40 to 50 grams of blood-sugar-raising carbohydrates to your diet, all of which can cause you to pack on belly fat and increase inflammation and insulin resistance – boosting the risk for diabetes and heart disease. Bottom line: Soda and sugary fruit drinks are some of the worst drinks for people with diabetes.</p> <p>“If you have diabetes, cutting out soda and other sugar-sweetened drinks is one of the most powerful ways to control blood sugar, lose weight, and improve your health,” says Ginn. “Switching to healthier drinks can save hundreds of calories and a lot of carbohydrates. It’s often one of my first goals when I work with someone newly diagnosed with diabetes.”</p> <p><strong>How much: </strong>None, ideally. Think of soft drink as you would a decadent dessert that you might indulge a taste of once in a blue moon. If you have a soda habit, cut back by drinking a smaller size for a week or two, or mixing half regular soda with half diet soda or soda water to reduce your kilojoule and carb intake. Aim to go sugar-free: Water and soda water (including zero-calorie fruit-flavoured types) are ideal, and diet soft drink is an option for diabetic drinks but don’t exceed one a day.</p> <h4>Drink less: Fruit juice</h4> <p>Your mum served up OJ every day with breakfast, and you grew to love it. The labels display tempting photos of colourful fruit. But are juices healthy diabetic drinks for blood sugar and weight control? A regular juice habit is associated with an increased risk of type 2 diabetes, according to a study published in Diabetes Care. In terms of nutrition, a piece of real fruit is a better deal (and science is backing that people with diabetes can, and should, eat fruit). A 125ml serving of 100 percent orange juice has 247 kilojoules, 13.6 grams carbohydrates, and no fibre; compare that to a small fresh orange, which has 188 kilojoules, 11 grams carbohydrates, and 2 grams of blood-sugar-controlling fibre. That said, people with diabetes can indulge in a little 100 percent fruit juice once in a while, says registered dietitian Dawn Menning, a certified diabetes educator. “They should just know the amount of juice they are consuming and factor the number of carbohydrates into their eating plan,” she says.</p> <p><strong>How much: </strong>Juice lovers, eat fruit or switch to a low-sodium veggie juice, which is much lower in calories and carbohydrates than fruit juice. If you’re really craving juice, try a 125ml serving with a meal. Test your blood sugar afterward, and then repeat with the same meal for the next three or four days. If your blood sugar doesn’t rise more than 35 to 50 points, a little juice could be fine.</p> <p><em>Image: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/diabetes/the-best-and-worst-drinks-for-people-with-diabetes" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

We were told we’d be riding in self-driving cars by now. What happened to the promised revolution?

<p>According to <a href="https://electrek.co/2015/12/21/tesla-ceo-elon-musk-drops-prediction-full-autonomous-driving-from-3-years-to-2/">predictions</a> <a href="https://www.vanityfair.com/news/2016/09/lyfts-president-says-car-ownership-will-all-but-end-by-2025">made</a> nearly a decade ago, we should be riding around in self-driving vehicles today. It’s now clear the autonomous vehicle revolution was overhyped.</p> <p>Proponents woefully underestimated the technological challenges. It turns out developing a truly driverless vehicle is hard.</p> <p>The other factor driving the hype was the amount of money being invested in autonomous vehicle startups. By 2021, it was estimated more than <a href="https://www.washingtonpost.com/outlook/2022/02/04/self-driving-cars-why/">US$100 billion</a> in venture capital had gone into developing the technology.</p> <p>While advances are being made, it is important to understand there are multiple levels of autonomy. Only one is truly driverless. As established by <a href="https://www.sae.org/blog/sae-j3016-update">SAE International</a>, the levels are:</p> <ul> <li> <p>level 0 — the driver has to undertake all driving tasks</p> </li> <li> <p>level 1, hands on/shared control — vehicle has basic driver-assist features such as cruise control and lane-keeping</p> </li> <li> <p>level 2, hands off – vehicle has advanced driver-assist features such as emergency braking, adaptive cruise control, auto park assist and traffic-jam assist</p> </li> <li> <p>level 3, eyes off — vehicle drives itself some of the time</p> </li> <li> <p>level 4, mind off — vehicle drives itself most of the time</p> </li> <li> <p>level 5, steering wheel option — vehicle drives itself all the time.</p> </li> </ul> <h2>Why the slow progress?</h2> <p>It’s estimated the technology to deliver safe autonomous vehicles is about <a href="https://www.theguardian.com/technology/2022/mar/27/how-self-driving-cars-got-stuck-in-the-slow-lane">80% developed</a>. The last 20% is increasingly difficult. It will take a lot more time to perfect.</p> <p>Challenges yet to be resolved involve unusual and rare events that can happen along any street or highway. They include weather, wildlife crossing the road, and highway construction.</p> <p>Another set of problems has emerged since <a href="https://www.forbes.com/sites/simonmainwaring/2022/08/22/cruise-ride-hailing-goes-green-and-driverless/?sh=6a7439376843">Cruise</a> and <a href="https://www.theverge.com/2022/11/19/23467784/waymo-provide-fully-driverless-rides-san-francisco-california">Waymo</a> launched their autonomous ride-hailing services in San Francisco. The US National Highway Traffic and Safety Administration <a href="https://techcrunch.com/2022/12/16/cruises-autonomous-driving-tech-comes-under-scrutiny-from-safety-regulators/">opened an investigation</a> in December 2022, only six months after the <a href="https://www.theguardian.com/technology/2022/jun/03/california-driverless-taxi-cars-san-francisco">services were approved</a>. It cited incidents where these vehicles “may have engaged in inappropriately hard braking or became immobilized”.</p> <p>The San Francisco County Transportation Authority <a href="https://www.nytimes.com/2023/02/01/technology/self-driving-taxi-san-francisco.html" target="_blank" rel="noopener">stated</a>, "[I]n the months since the initial approval of autonomous taxi services in June 2022, Cruise AVs have made unplanned and unexpected stops in travel lanes, where they obstruct traffic and transit service and intrude into active emergency response scenes, including fire suppression scenes, creating additional hazardous conditions."</p> <p>In several cases, Cruise technicians had to be called to move the vehicles.</p> <h2>What’s happening now?</h2> <p>Active autonomous vehicle initiatives can be grouped into two categories: ride-hailing services (Cruise, Waymo and Uber) and sales to the public (Tesla).</p> <p>Cruise is a subsidiary of General Motors founded in 2013. As of September 2022, it operated 100 robotaxis in San Francisco and had plans to increase its fleet to 5,000. Critics said this would increase city traffic.</p> <p>Cruise also began to offer services in Chandler (a Phoenix suburb), Arizona, and Austin, Texas, in December 2022.</p> <p>Waymo, formerly the Google Self-Driving Car Project, was founded in January 2009. The company lost <a href="https://www.theverge.com/2022/11/11/23453262/waymo-av-driverless-taxi-phoenix-california-dmv-progress">US$4.8 billion in 2020 and US$5.2 billion in 2021</a>.</p> <p>Waymo One provides autonomous ride-hailing services in <a href="https://www.theverge.com/2023/2/28/23617278/waymo-self-driving-driverless-crashes-av">Phoenix as well as San Francisco</a>. It plans to expand into <a href="https://www.theverge.com/2022/10/19/23410677/waymo-los-angeles-autonomous-robotaxi-service-launch">Los Angeles</a> this year.</p> <p>Uber was a major force in autonomous vehicle development as part of its business plan was to replace human drivers. However, it ran into problems, including a crash in March 2018 when a self-driving Uber killed a woman walking her bicycle across a street in Tempe, Arizona. In 2020, Arizona Uber sold its AV research division to Aurora Innovation.</p> <p>But in October 2022 Uber got back into autonomous vehicles by <a href="https://www.forbes.com/sites/samabuelsamid/2022/10/06/motional-and-uber-announce-10-year-deal-to-deploy-automated-vehicles-in-multiple-us-markets/?sh=44d83a84273e">signing a deal</a> with Motional, a joint venture between Hyundai and Aptiv. Motional will provide autonomous vehicles for Uber’s ride-hailing and delivery services.</p> <p>Lyft, the second-largest ride-sharing company after Uber, operates in the US and Canada. Like Uber, Lyft had a self-driving unit and in 2016, Lyft co-founder John Zimmer <a href="https://www.vanityfair.com/news/2016/09/lyfts-president-says-car-ownership-will-all-but-end-by-2025">predicted</a> that by 2021 the majority of rides on its network would be in such vehicles (and private car ownership would “all but end” by 2025). It didn’t happen. By 2021, Lyft had also <a href="https://techcrunch.com/2021/04/26/lyft-sells-self-driving-unit-to-toyotas-woven-planet-for-550m/">sold its self-driving vehicle unit</a>, to Toyota.</p> <p>In 2022, Zimmer <a href="https://techcrunch.com/2022/10/20/lyft-co-founder-says-autonomous-vehicles-wont-replace-drivers-for-at-least-a-decade/">said</a> the technology would not replace drivers for at least a decade. However, Lyft did partner with Motional in August 2022 to launch <a href="https://www.prnewswire.com/news-releases/lyft-and-motional-deliver-the-first-rides-in-motionals-new-all-electric-ioniq-5-autonomous-vehicle-301606519.html">robotaxis in Las Vegas</a> and <a href="https://www.reuters.com/business/autos-transportation/lyft-motional-launch-robotaxi-service-los-angeles-2022-11-17/">Los Angeles</a>.</p> <p>Telsa is the <a href="https://www.ev-volumes.com/">world leader in sales</a> of battery electric vehicles. It also purports to sell vehicles with full automation. However, by the end of 2022, no level 3, 4 or 5 vehicles were for sale in the United States.</p> <p>What Telsa offers is a full self-driving system as a US$15,000 option. Buyers acknowledge they are buying a beta version and assume all risks. If the system malfunctions, Telsa does not accept any responsibility.</p> <p>In February 2023, the National Highway Traffic Safety Administration <a href="https://amp.theguardian.com/technology/2023/feb/16/tesla-recall-full-self-driving-cars">found</a>, "[Fully self-driving] beta software that allows a vehicle to exceed speed limits or travel through intersections in an unlawful or unpredictable manner increases the risk of a crash."</p> <p>This led to Tesla <a href="https://www.theguardian.com/technology/2023/feb/16/tesla-recall-full-self-driving-cars">recalling 362,000 vehicles</a> to update the software.</p> <p>Another setback for autonomous vehicle sales to the public was the October 2022 announcement that Ford and VW had decided to <a href="https://techcrunch.com/2022/10/26/ford-vw-backed-argo-ai-is-shutting-down/">stop funding autonomous driving technology company Argo AI</a>, resulting in its closure. Both Ford and VW decided to shift their focus from level 4 automation to levels 2 and 3.</p> <h2>So, what can we expect next?</h2> <p>Autonomous vehicle development will continue, but with less hype. It’s being recognised as more an evolutionary process than a revolutionary one. The increasing cost of capital will also make it harder for autonomous vehicle startups to get development funds.</p> <p>The areas that appear to be making the best progress are autonomous ride-hailing and heavy vehicles. Self-driving car sales to the public are <a href="https://www.drive.com.au/news/level-4-self-driving-technology-mercedes-benz/">further down the track</a>.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/we-were-told-wed-be-riding-in-self-driving-cars-by-now-what-happened-to-the-promised-revolution-201088" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

The wellbeing ‘pandemic’ – how the global drive for wellness might be making us sick

<p>Are we in the midst of a wellbeing pandemic? The question may seem curious, even contradictory. But look around, the concept is everywhere and spreading: in the media, in government institutions and transnational organisations, in schools, in workplaces and in the marketplace. </p> <p>To be clear, it’s not just wellbeing’s infectiousness in public discourse that makes it pandemic-like. It’s also the genuine malaise that can be caused by the term’s misuse and exploitation.</p> <p>Do you sense, for example, that your wellbeing is increasingly being scrutinised by peers, managers and insurance companies? Are you noticing an increasing number of advertisements offering products and services that promise enhanced wellbeing through consumption? If so, you’re not alone. </p> <p>But we also need to ask whether this obsession with wellbeing is having the opposite to the desired effect. To understand why, it’s important to look at the origins, politics and complexities of wellbeing, including its strategic deployment in the process of what we call “<a href="https://otagouni-my.sharepoint.com/personal/jacst99p_registry_otago_ac_nz/Documents/Documents/SJ-Wellness/SJ-Conversation-Wellbeing/Jackson-Sam-Dawson-Porter-Frontiers-Sociology-Wellbeing-2022.pdf">wellbeing washing</a>”.</p> <h2>The halo effect</h2> <p>While concerns about wellbeing can be traced to antiquity, the term has emerged as a central feature of contemporary social life. One explanation is that it is often conflated with concepts as diverse as happiness, quality of life, life satisfaction, human flourishing, mindfulness and “wellness”. </p> <p>Wellbeing is flexible, in the sense that it can be easily inserted into a diverse range of contexts. But it’s also surrounded by a kind of halo, automatically bestowed with a positive meaning, similar to concepts such as motherhood, democracy, freedom and liberty. </p> <p>To contest the value and importance of such things is to risk being labelled a troublemaker, a non-believer, unpatriotic or worse.</p> <p>These days, there are two main concepts of wellbeing. The first – subjective wellbeing – emphasises a <a href="https://www.frontiersin.org/articles/10.3389/fsoc.2022.950557/full#B21">holistic measure</a> of an individual’s mental, physical and spiritual health. This perspective is perhaps best reflected in the World Health Organization’s <a href="https://www.corc.uk.net/outcome-experience-measures/the-world-health-organisation-five-well-being-index-who-5/">WHO-5 Index</a>, designed in 1998 to measure people’s subjective wellbeing according to five states: cheerfulness, calmness, vigour, restfulness and fulfilment.</p> <p>Translated into more than 30 languages, the overall influence of the WHO-5 Index should not be underestimated; both governments and corporations have embraced it and implemented policy based on it. </p> <p>But the validity of the index, and others like it, has been questioned. They’re prone to oversimplification and a tendency to marginalise alternative perspectives, including Indigenous approaches to physical and mental health.</p> <h2>Individual responsibility</h2> <p>The second perspective – objective wellbeing – was a response to rising social inequality. It focuses on offering an <a href="https://www.frontiersin.org/articles/10.3389/fsoc.2022.950557/full#B60">alternative to GDP</a> as a measure of overall national prosperity. </p> <p>One example of this is New Zealand’s <a href="https://www.treasury.govt.nz/information-and-services/nz-economy/higher-living-standards/our-living-standards-framework">Living Standards Framework</a>, which is guided by four operating principles: distribution, resilience, productivity and sustainability. These new and purportedly more progressive measures of national economic and social outcomes signal societal change, optimism and hope.</p> <p>The trouble with such initiatives, however, is that they remain rooted within a particular neoliberal paradigm in which individual behaviour is the linchpin for change, rather than the wider political and economic structures around us.</p> <p>Arguably, this translates into more monitoring and “disciplining” of personal actions and activities. Intentionally or not, many organisations interpret and use wellbeing principles and policies to reinforce existing structures and hierarchies. </p> <p>Consider how the wellbeing agenda is playing out in your organisation or workplace, for example. Chances are you have seen the growth of new departments, work units or committees, policies and programs, wellness workshops – all supposedly linked to health and wellbeing. </p> <p>You may even have noticed the creation of new roles: wellbeing coaches, teams or “champions”. If not, then “lurk with intent” and be on the lookout for the emergence of yoga and meditation offerings, nature walks and a range of other “funtivities” to support your wellbeing. </p> <h2>Wellbeing washing</h2> <p>The danger is that such initiatives now constitute another semi-obligatory work task, to the extent that non-participation could lead to stigmatisation. This only adds to stress and, indeed, unwellness. </p> <p>Deployed poorly or cynically, such schemes represent aspects of “wellbeing washing”. It’s a strategic attempt to use language, imagery, policies and practices as part of an organisation’s “culture” to connote something positive and virtuous. </p> <p>In reality, it could also be designed to enhance productivity and reduce costs, minimise and manage reputational risk, and promote <a href="https://otagouni-my.sharepoint.com/personal/jacst99p_registry_otago_ac_nz/Documents/Documents/SJ-Wellness/SJ-Conversation-Wellbeing/Jackson-Sam-Dawson-Porter-Frontiers-Sociology-Wellbeing-2022.pdf">conformity, control and surveillance</a>. </p> <p>Ultimately, we argue that wellbeing now constitutes a “field of power”; not a neutral territory, but a place where parties advance their own interests, often at the expense of others. As such, it’s essential that scholars, policymakers and citizens explore, as one author <a href="https://www.google.com.au/books/edition/Measuring_Wellbeing/lWBXjk1nocIC?hl=en&amp;gbpv=1&amp;dq=%E2%80%9Cwhat+and+whose+values+are+represented,+which+accounts+dominate,+what+is+their+impact+and+on+whom%E2%80%9D&amp;pg=PA4&amp;printsec=frontcover">put it</a>, “what and whose values are represented, which accounts dominate, what is their impact and on whom”. </p> <p>Because if wellbeing is becoming a pandemic, we may well need the “vaccine” of critical reflection.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/the-wellbeing-pandemic-how-the-global-drive-for-wellness-might-be-making-us-sick-198662" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Why do people tailgate? A psychologist explains what’s behind this common (and annoying) driving habit

<p>It’s hot, you’ve had a battle to get the kids in the car, and now you’re going to be late for the family lunch. </p> <p>You turn onto the freeway only to get stuck behind a slow driver in the fast lane. You want them to move over or speed up, so you drive a little closer. Then closer. Then so close it would be difficult to avoid hitting them if they stopped suddenly. </p> <p>When that doesn’t work you honk the horn. Nothing. Finally, frustrated, you dart into the left lane and speed past them.</p> <p>Today was one of those days where many small annoyances have led to you being aggressive on the road. This isn’t how you usually drive. So why was today different?</p> <h2>Aren’t holidays supposed to be relaxing?</h2> <p>Holiday driving may look a lot different to your usual commute. It may involve driving longer distances, or involve more frequent driving with more passengers than usual in the car. </p> <p>Holiday driving comes with <a href="https://www.bitre.gov.au/publications/ongoing/road_deaths_australia_monthly_bulletins">increased risk</a> (road deaths tend to spike during the holidays). That’s why news bulletins often carry the latest “road toll” figures around public holidays. </p> <p>But whether you drive differently to normal comes down to the value you place on your <a href="https://doi.org/10.1016/S0001-4575(03)00037-X">time</a>, rather than when you drive. </p> <p>If you are in a rush, your time becomes more precious because you have less of it. If something, or someone, infringes on that time, you may become frustrated and aggressive.</p> <p>This is basic human psychology. You can get angry when someone gets in the way of what you are trying to achieve. You get angrier when you think they are acting <a href="https://doi.org/10.1037/0033-2909.106.1.59">unfairly or inappropriately</a>.</p> <p>Usually before you respond, you evaluate what has happened, asking who is at fault and if they could have done things differently. </p> <p>But when you are driving, you have less time and resources to make detailed evaluations. Instead, you make quick judgements of the situation and how best to deal with it. </p> <p>These judgements can be based on how you are <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0022-3514.81.1.146">feeling</a> at the time. If you are frustrated before getting in the car, you are likely to be easily frustrated while driving, blame other drivers more for your circumstances, and express this through aggressive driving.</p> <p>Tailgating and speeding <a href="https://doi.org/10.1016/S0005-7967(01)00063-8">are examples</a> of this aggression.</p> <p>A driver frustrated by the perception that someone is driving too slowly, or in the wrong lane, might speed past the offending driver, and maintain this speed for some time <a href="https://doi.org/10.1080/02699931.2010.551184">after the event</a>. </p> <p>Aggressive tailgating may be seen as reprimanding the driver for their perceived slow speeds, or to encourage them to move out of the way. </p> <p>The problem is, when you are angry, you underestimate the risk of these behaviours, while <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0022-3514.81.1.146">over-estimating</a> how much control you have of the situation. It’s not worth the risk. </p> <p>A <a href="https://doi.org/10.1073/pnas.1513271113">study of real-world driving</a> shows both tailgating and speeding increase the odds of being in a crash more than if driving while holding or dialling a mobile phone. Drivers who are tailgating or speeding have a 13 to 14-fold increase in odds of being in a crash, compared to when they are driving more safely.</p> <h2>Here’s what you can do</h2> <p>One way to stay safe on the roads these holidays is to recognise the situations that may lead to your own dangerous behaviours. </p> <p>The Monash University Accident Research Centre has <a href="https://doi.org/10.1016/j.jsr.2022.07.011">developed a program</a> to help drivers reduce their aggressive driving. This helps drivers develop their own strategies to stay calm while driving, recognising that one strategy is unlikely to suit every driver. </p> <p>Almost 100 self-identified aggressive drivers <a href="https://www.sciencedirect.com/science/article/pii/S0022437522000998?via%3Dihub">developed</a> four types of tips to remain calm while driving:</p> <ol> <li> <p>before driving: tips include better journey planning, allowing enough time for the trip and recognising how you are feeling before you get in the car </p> </li> <li> <p>while driving: this includes travelling in the left lane to avoid slow drivers in the right lane, or pulling over when feeling angry</p> </li> <li> <p>in your vehicle: such as deep breathing or listening to music</p> </li> <li> <p>‘rethinking’ the situation: acknowledge that in some situations, the only thing you can change is how you think about it. For example, ask yourself is it worth the risk? Or personalise the other driver. What if that was your loved one in the car in front?</p> </li> </ol> <p>Four months after completing the program, drivers reported less anger and aggression while driving than before the program. The strategies that worked best for these drivers were listening to music, focusing on staying calm and rethinking the problem.</p> <p>A favourite rethink was a 5x5x5 strategy. This involved asking yourself whether the cause of your anger will matter in five minutes, five hours or five days. If it is unlikely to matter after this time, it is best to let go. </p> <p>The holidays are meant to be relaxing and joyous. Let’s not jeopardise that through reactions to other drivers.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/why-do-people-tailgate-a-psychologist-explains-whats-behind-this-common-and-annoying-driving-habit-193462" target="_blank" rel="noopener">The Conversation</a>. </em></p>

6 things that can happen to your body when you don’t drink enough water

<p>While there is much talk about how much water one should drink per day (most experts suggest around two litres) have you ever thought what would actually happen to your body if you don’t get enough H2O? Here we chart six things that can go wrong if you don’t hit the recommended daily intake.</p> <p>1. You're more likely to have health problems. Higher water intake has been linked to decreased chances of kidney stones, urinary and colon cancer, and heart attacks.</p> <p>2. Your metabolism stagnates. In independent studies for his 2010 book The Water Secret (Wiley), Dr. Howard Murad found that a person's basal metabolic rate (the calories burned while at rest) speeds up as the body becomes more hydrated. </p> <p>3. You'll have to think harder to complete the same tasks. At the Institute of Psychiatry at King's College London in 2011, scientists found that the brains of dehydrated teenagers had shrunk away from their skulls, and that when asked to play a problem-solving game, they performed just as well as those who drank enough, but engaged more of their brains to do so. (Drinking water restores the brain to its normal size.)</p> <p>4. You eat more. A study of 45 adults funded by the Institute for Public Health and Water Research found that those who drank two eight-ounce glasses of water before each meal consumed 75 to 90 fewer calories while eating. (Over three months, water-drinkers lost an average of five pounds more than the dieters who were parched.)</p> <p>5. You look more wrinkled. In researching his book, Dr. Murad also found that water plumps skin, fills in fine lines and wrinkles, and enlivens a dull complexion.</p> <p>6. You're in a bad mood. In 2009, researchers at Tufts University in Medford, MA, asked members of the men's and women's crew teams to engage in 60 to 75 minutes of high-impact aerobic exercise without drinking enough water first. Others were properly hydrated. The dehydrated group was more likely to report feeling fatigued, confused, angry, depressed or tense. </p> <p><em>Image credits: Getty Images</em></p>

Laser hack of self-driving cars can ‘delete’ pedestrians

<p>Although a city filled with entirely self-driving cars is still in the realm of science fiction, more and more cars are <a href="https://en.wikipedia.org/wiki/Tesla_Autopilot" target="_blank" rel="noopener">coming with ‘self-driving’ features so</a> it’s a little alarming to learn that there are ways to use lasers to mess with the technology the cars use to detect its surroundings.</p> <p><a href="https://arxiv.org/abs/2210.09482" target="_blank" rel="noopener">In a study uploaded to arXiv</a> by a team of researchers in the US and Japan, researchers were able to trick the ‘victim vehicle’ (their words not ours) into not seeing a pedestrian or other object in its way.</p> <p>Most self-driving cars use LIDAR to be able to ‘see’ around them by sending out a laser light and then recording the reflection from objects in the area. The time it takes for the light to reflect back gives the system information about how far away the object is.</p> <p>This new ‘hack’ or spoof works because a perfectly timed laser shined onto a LIDAR system can create a blind spot large enough to hide an object like a pedestrian.</p> <p>“We mimic the LIDAR reflections with our laser to make the sensor discount other reflections that are coming in from genuine obstacles,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said University of Florida cyber security researcher professor Sara Rampazzi.</a></p> <p>“The LIDAR is still receiving genuine data from the obstacle, but the data are automatically discarded because our fake reflections are the only one perceived by the sensor.”</p> <div class="newsletter-box"> <div id="wpcf7-f6-p221287-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>Although the technology is relatively simple, the attack isn’t an easy one. The team demonstrated the attack up to 10 meters away from the car, but the device must be perfectly timed, and move with the car to be able to keep the laser pointing the right way.</p> <p>The researchers have already told manufacturers about this potential exploit and have suggested ways to be able to minimise the problem. Manufacturers might be able to teach the software to look for the tell-tale signatures of the spoofed reflections added by the laser attack.</p> <p>“Revealing this liability allows us to build a more reliable system,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said first author, University of Michigan computer scientist Yulong Cao.</a></p> <p>“In our paper, we demonstrate that previous defence strategies aren’t enough, and we propose modifications that should address this weakness.”</p> <p>This unfortunately isn’t the first time that researchers have found <a href="https://cosmosmagazine.com/news/tricking-driverless-car-sensors/" target="_blank" rel="noreferrer noopener">vulnerabilities with LIDAR sensors on self-driving cars</a>, but as more of these problems are uncovered and fixed, the technology will hopefully end up safer in the long run.</p> <p>The research is to be presented next year at the <a href="https://www.usenix.org/conference/usenixsecurity23" target="_blank" rel="noopener">2023 USENIX Security Symposium</a>.</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=221287&amp;title=Laser+hack+of+self-driving+cars+can+%E2%80%98delete%E2%80%99+pedestrians" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/technology/laser-hack-lidar-self-driving-cars-delete-pedestrians/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Jacinta Bowler.</em></p> <p><em>Image: Getty Images</em></p> </div>

Train driving dream comes true for brain tumour survivor

<p dir="ltr">Three years after doctors found a large tumour growing in his brain, seven-year-old Broly Blackmore has seen his dream of becoming a train driver come true.</p> <p dir="ltr">The young boy from Hallett, South Australia, had the tumour removed when he was just four years old after he collapsed and was rushed to hospital by helicopter.</p> <p dir="ltr">If it wasn’t removed that night, doctors told his mother, Corrine Maidment, that he wouldn’t make it.</p> <p dir="ltr">In the years since, Broly’s life has become relatively normal, albeit with regular brain scans and physio trips - and he has had his wish of driving a train granted by the Starlight Foundation.</p> <p dir="ltr">The seven-year-old went on a trip on the Pichi Richi steam train, travelling from Quorn to Port Augusta as a “trainee train driver”.</p> <p dir="ltr">"Ever since he was only a couple of months old everything has always been about trains … diesels aren't as good as steam trains apparently," Ms Maidment said, adding that he barely slept the night before the big day.</p> <p dir="ltr">"According to everyone in the train, they weren't allowed to do anything without his say so … at one point, he told the fireman, the guy who does the coal, 'That's my seat. I need to sit there'.</p> <p dir="ltr">"He was boss for the day." </p> <p dir="ltr">The Pichi Richi railway, an outback steam train experience that has been operating since 1973, later shared a sweet photo of Broly on the train.</p> <p dir="ltr">“Last Sunday, Pichi Richi Railway was able to grant a wish for a very special visitor, 7 year old Broly who was having his wish granted with help from Starlight Children's Foundation Australia’s ‘Wishgranting Program’,” the railway <a href="https://www.facebook.com/PichiRichiRailway/posts/pfbid032C45MeP339xWYPL321ZTFjXXsehYJh7pWe2xkX812DkCLCBZgZyp8UVNGVzF7ztvl">wrote</a>.</p> <p dir="ltr">“Broly loves trains so Starlight contacted Pichi Richi Railway and Broly was lucky enough to ride in the cab of engine W934 for the day with our crew on the Pichi Richi Explorer service. </p> <p dir="ltr">“A very special day for our crew, Broly and his family.”</p> <p dir="ltr">Although Broly’s wish was given to him while he was in hospital, Ms Maidment said they had waited until he was old enough to decide how he wanted to spend it.</p> <p dir="ltr">"He's had the wish sitting there since he was in the hospital ... but we wanted to wait until he was old enough to make a decision himself so he'd know what the wish was and he'd remember it," she said. </p> <p><span id="docs-internal-guid-4354a857-7fff-0466-bb9f-4dd255b3ba47"></span></p> <p dir="ltr"><em>Images: Blackmore family, Starlight Foundation, Pichi Richi Railway (Facebook)</em></p>

7 signs you’re drinking too much coffee

<h2>You feel anxious</h2> <p>Ruminating about an upcoming event or deadline can fuel your desire to grab a comforting mug of coffee. Yet, the National Institute of Mental Health in the US recommends that people who suffer from anxiety avoid caffeine. Why? Drinking too much coffee can actually worsen the effects of anxiety, either by robbing you of proper sleep or triggering your flight or fight response. In a 1990 study published in Psychosomatic Medicine, 25 men were given a moderate dose of caffeine or a placebo before a stressful task. The men, who were all regular coffee drinkers, had higher blood pressure, stress hormones, and about double the reported stress level with the caffeine compared with the placebo.</p> <h2>Your stomach hurts</h2> <p>You may associate stomach pains with spoiled food or PMS cramps. You should add your morning cuppa to that list as well. In 2017, European scientists found that certain compounds in coffee stimulate the secretion of stomach acid by your stomach cells. Taking an over-counter medication like Tums can neutralise the acid short-term, but if you suspect drinking too much coffee is making your stomach hurt, think about changing your coffee consumption habits.</p> <h2>Your heart is racing</h2> <p>The feeling that your heart is beating too fast can be frightening. It may feel like your heart is trying to escape from your ribcage. These heart palpitations can be caused by the consumption of too much coffee and caffeine, nicotine, and even alcohol. In some cases, a racing heart can lead to dizziness and even fainting spells. According to a 2017 study in the journal Frontiers in Psychiatry, 94 per cent of doctors recommend patients experiencing the fluttering heart beats stop consuming caffeine.</p> <h2>You have diarrhoea</h2> <p>Most people know that coffee can help keep you regular, thanks to its laxative properties. Drink more than two or three cups a day, though, and you might get diarrhoea, according to the International Foundation for Gastrointestinal Disorders. If you find your bathroom issues become unmanageable, the IFFGD recommends gradual withdrawal from caffeine.</p> <h2>You can’t sleep</h2> <p>Insomnia can be a telltale sign of too much coffee. Even if you swear coffee doesn’t have any effect on you, this tasty drink can still wreak havoc on your sleep cycle. Coffee’s half-life is five hours, according to the American Academy of Sleep Medicine. That means it can take several more hours for the stimulant to completely leave your system. This can increase the number of times you wake up during the night, and decrease overall time asleep. To solve this problem, try to drink that last cup of coffee no later than noon.</p> <h2>You’ve got the jitters</h2> <p>Coffee makes you feel more alert, but sometimes that feeling turns into too much of a good thing. This is where the jitters come in. Caffeine speeds up your central nervous system, causing you to feel jumpy. Skip that fourth cup and stop the shakes.</p> <h2>You get headaches</h2> <p>A moderate amount of caffeine helps relieve a headache, by helping pain-relief medications work better, according to a study in The Journal of Headache and Pain. That’s why you’ll find caffeine as an ingredient in many over-the-counter headache drugs. However, if you drink too much coffee for a sustained amount of time (getting a daily excess of 500 mg of caffeine, or the equivalent of five cups of coffee), you can go through caffeine withdrawal. The symptoms include headaches and fatigue, found Johns Hopkins researchers. Slowly decrease your caffeine intake – and look at all the possible sources in your diet, including coffee, headache drugs, tea, soft drink, and energy drinks.</p> <p><strong>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/7-signs-youre-drinking-too-much-coffee" target="_blank" rel="noopener">Reader's Digest</a>. </strong></p> <p><em>Image: Shutterstock</em></p>

Mortali-tea! Black tea drinking linked to lower risk of dying

<p>The health benefits of green tea are well-established, but black tea might be a good idea too, according to a new analysis.</p> <p>The study, published in Annals of Internal Medicine, draws on data from nearly half a million people to find a link between black tea drinking and lower mortality risk.</p> <p>The researchers, who are based at the US National Institute of Health, examined data from the long-term UK Biobank study, which tracked a cohort of 502,488 UK residents aged between 40 and 69.</p> <p>Between 2006 and 2010, participants in this study regularly logged a range of lifestyle, and health-related information via touchscreens at assessment centres. This information included tea drinking, by number of cups per day.</p> <p>Among the 498,043 participants who logged tea-drinking information, 85% reported regularly drinking tea. Nearly a fifth of participants (19%) reported drinking more than six cups of tea per day.</p> <p>A separate survey of a smaller cohort of participants suggested that 89% of the tea drinkers drank black tea, while 7% drank green tea.</p> <p>According to the UN, the UK consumes around 100,000 tonnes of tea each year – or about 1.5 kilograms per person.</p> <p>The American researchers combined the tea-drinking information in the UK with mortality data.</p> <p>Once they’d adjusted for age and demographics, they found that participants who drank at least two cups of tea per day had a 9-13% lower risk of dying.</p> <p>Drinking 2-3 cups per day was associated with the lowest mortality risk, but even drinking 10 or more cups was linked to a lower mortality risk than drinking no tea at all.</p> <p>In their paper, the researchers say that their findings reflect similar studies based in China and Japan, where green tea is much more common than black.</p> <p>“Fewer studies have assessed tea intake and mortality in populations where black tea is predominantly consumed, such as in the United States and Europe, and results have varied across studies,” write the researchers.</p> <p>They point out, however, that they didn’t track some “potentially important aspects” like tea strength or cup size, making it harder to draw precise conclusions.</p> <p>While the study is observational and thus can’t establish a cause, the researchers point out that the polyphenols and flavonoids in black tea have been linked to a variety of health benefits in small randomized-control trials – including lower cholesterol, and a lower risk of carcinogenesis and type 2 diabetes.</p> <p>“These findings provide reassurance to tea drinkers and suggest that black tea can be part of a healthy diet,” write the researchers.</p> <p><strong>This article originally appeared in <a href="https://cosmosmagazine.com/health/black-tea-mortality-risk/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian.</strong></p> <p><em>Image: Shutterstock</em></p>
