Is stress turning my hair grey?

<p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>When we start to go grey depends a lot on <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">genetics</a>.</p> <p>Your first grey hairs <a href="https://elifesciences.org/articles/67437">usually appear</a> anywhere between your twenties and fifties. For men, grey hairs <a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">normally</a> start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.</p> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">rapid greying</a> usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?</p> <p>You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.</p> <h2>What gives hair its colour?</h2> <p>Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of <a href="https://www.sciencedirect.com/science/article/pii/S1534580720301040">stem cells</a>:</p> <ul> <li>keratinocytes, which produce <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, the protein that makes and regenerates hair strands</li> <li>melanocytes, which produce <a href="https://my.clevelandclinic.org/health/body/22615-melanin">melanin</a>, the pigment that colours your hair and skin.</li> </ul> <p>There are <a href="https://www.ncbi.nlm.nih.gov/books/NBK459156/">two main types</a> of melanin that <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">determine hair colour</a>. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.</p> <p>The <a href="https://theconversation.com/studying-the-complex-genetics-behind-hair-colour-reveals-how-melanin-affects-us-171088#:%7E:text=Eumelanin%20is%20also%20known%20as%20the%20brown-black%20pigment%2C,is%20due%20to%20low%20amounts%20of%20both%20pigments.">amount of the different pigments</a> determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.</p> <h2>So what makes our hair turn grey?</h2> <p>As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.</p> <p>As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.</p> <p>Unpigmented hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">looks grey</a>, white or silver because light reflects off the keratin, which is pale yellow.</p> <p>Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">irregular</a> as the stem cells change with age.</p> <p>Interestingly, grey hair also grows faster than pigmented hair, but it <a href="https://elifesciences.org/articles/67437">uses more energy</a> in the process.</p> <h2>Can stress turn our hair grey?</h2> <p>Yes, stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">cause your hair to turn grey</a>. This happens when <a href="https://faseb.onlinelibrary.wiley.com/doi/epdf/10.1096/fj.05-4039fje">oxidative stress</a> damages hair follicles and stem cells and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.839859/full">stops them producing</a> melanin.</p> <p>Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">caused by</a> psychological or emotional stress as well as autoimmune diseases.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">Environmental factors</a> such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.</p> <p>Melanocytes are <a href="https://elifesciences.org/articles/67437">more susceptible to damage</a> than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.</p> <p>Scientists have been able to link less pigmented sections of a hair strand to <a href="https://elifesciences.org/articles/67437">stressful events in a person’s life</a>. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.</p> <h2>4 popular ideas about grey hair – and what science says</h2> <p><strong>1. Does plucking a grey hair make more grow back in its place?</strong></p> <p>No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the <a href="https://my.clevelandclinic.org/health/body/23435-hair-follicle">root</a>. It grows from the hair follicle.</p> <p>Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.</p> <p>It’s possible frequent plucking could make your hair <a href="https://pubmed.ncbi.nlm.nih.gov/18713071/">grey earlier</a>, if the cells that produce melanin are damaged or exhausted from too much regrowth.</p> <p><strong>2. Can my hair can turn grey overnight?</strong></p> <p>Legend says Marie Antoinette’s hair went <a href="https://www.healthline.com/health/marie-antoinette-syndrome">completely white</a> the night before the French queen faced the guillotine – but this is a myth.</p> <p>Melanin in hair strands is chemically stable, meaning it can’t transform instantly.</p> <p>Acute psychological stress does rapidly deplete melanocyte stem cells <a href="https://www.nature.com/articles/s41586-020-1935-3">in mice</a>. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of <a href="https://www.medicalnewstoday.com/articles/326764">about 1 cm per month</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">Not all hair</a> is in the growing phase at any one time, meaning it can’t all go grey at the same time.</p> <p><strong>3. Will dyeing make my hair go grey faster?</strong></p> <p>This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9953601/">depends on the dye</a>.</p> <p>Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.</p> <p>Accumulation of hydrogen peroxide and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10232955/">other hair dye chemicals</a> in the hair follicle <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">can damage</a> melanocytes and keratinocytes, which can cause greying and hair loss.</p> <p><strong>4. Is it true redheads don’t go grey?</strong></p> <p>People with red hair also lose melanin as they age, but differently to those with black or brown hair.</p> <p>This is because the red-yellow and black-brown pigments are chemically different.</p> <p>Producing the brown-black pigment eumelanin is more complex and <a href="https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0749.2002.02017.x">takes more energy</a>, making it more susceptible to damage.</p> <p>Producing the red-yellow pigment (pheomelanin) causes <a href="https://www.sciencedirect.com/science/article/pii/S016953472030375X">less oxidative stress</a>, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.</p> <p>With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.</p> <p>Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.</p> <p>Eating <a href="https://www.healthline.com/health/melanin-in-hair#b-6-and-b-12">a healthy diet</a> may also help because vitamin B12, copper, iron, calcium and zinc all <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">influence melanin production and hair pigmentation</a>.<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/239100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate Professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Commonly overlooked estate planning matters

<p>Estate planning is a complex business, making it easy to overlook some important considerations, potentially with costly results.</p> <p>Aside from basic issues like forgotten assets (always keep written records) and inaccurate details (double check everything before signing), seven of the most commonly disregarded estate planning matters are as follows:</p> <ol> <li><strong>Wills</strong></li> </ol> <p>Unlike many younger people, for over sixties the more common issue is not the lack of a will, but one which is out of date.</p> <p>Out-of-date wills complicate matters for executors, can delay probate for your beneficiaries, and may not reflect your true wishes (imagine inadvertently leaving everything to your ex or omitting one or more grandkids!).</p> <p>Update your will as your circumstances change – relationships (divorce, new partner etc), births and deaths, adult children getting married or divorced, exiting a business, asset sales, and so on.</p> <p>Retirement often brings its own changes too – e.g. a sea or tree change, new boat or caravan – which also should be updated in your will.</p> <ol start="2"> <li><strong>Letter of wishes</strong></li> </ol> <p>Wills are typically not read until after a funeral. As such, a letter of wishes is a useful addition for loved ones to have accessible immediately after your death.</p> <p>It can cover everything from funeral arrangements, burial vs cremation, and where you wish to be laid to rest to outlining intentions longer term, such as how any underage children are to be raised and educated, or care arrangements for any pets.</p> <ol start="3"> <li><strong>Super beneficiaries</strong></li> </ol> <p>One of the biggest myths about superannuation is that it is covered by your will. </p> <p>Super is treated separately, meaning you must nominate your beneficiaries within your super fund. And update them as circumstances change.</p> <p>This can be useful for blended families – leaving your super to children/grandchildren from a past relationship without encroaching on the assets of your current partner.</p> <p>Without nominating beneficiaries, the funds could go somewhere else entirely – even to government coffers.</p> <ol start="4"> <li><strong>Advanced Health Directive (a ‘living will’)</strong></li> </ol> <p>Estate planning doesn’t just cover your wishes once you’re gone. Yet people often focus solely on this aspect and overlook how they want to be looked after in the event of ill health or injury preventing them from being able to make decisions (e.g. stroke, terminal illness, severe accident).</p> <p>An Advanced Health Directive can express your wishes and values on everything from life support and resuscitation to palliative care, medical treatments, and who you wish to be able to speak on your behalf. </p> <ol start="5"> <li><strong>Insurances</strong></li> </ol> <p>Rarely do people have adequate insurance coverage for their needs.</p> <p>There are insurances in super, which may cover death and permanent disability. Insurance of assets. Income protection insurance. And health insurance.</p> <p>It’s important to right-size your insurance for your current needs and adapt that cover as your circumstances change. That means:</p> <ul> <li>Taking out new policies for new assets and investments.</li> <li>Updating policy inclusions and exclusions, such as relating to age.</li> <li>Cancelling insurances you no longer need (e.g. sold assets or professional indemnity once you retire).</li> </ul> <ol start="6"> <li><strong>Tax implications</strong></li> </ol> <p>Because Australia has no inheritance tax, many people are lulled into a false sense of complicity over tax implications in estate planning matters.</p> <p>However, beneficiaries can be liable for both Capital Gains Tax and income tax on inherited assets – potentially outweighing the value of those assets altogether.</p> <p>Additionally, your own tax status should be considered. For instance, you may be paying more tax by holding an income-producing asset rather than transferring ownership to a loved one before you pass away.</p> <ol start="7"> <li><strong>Tailored professional advice</strong></li> </ol> <p>DIY will kits, self-titled “expert” authors, and avoiding advisers to save money overlook the true value of tailored, professional advice given the complexity of estate planning.</p> <p>You don’t know what you don’t know, meaning the margin for error is huge. And when it comes to money, tax and estate law, errors can be expensive indeed.</p> <p>A good lawyer, accountant and financial adviser can more than pay for themselves by helping you avoid overpaying taxes, complex legal disputes, insufficient asset protections and lost wealth creation opportunities.</p> <p>And given estate planning is ultimately about peace of mind, can you – or your family – really afford to overlook such valuable insight?</p> <p><em>Image credits: Shutterstock</em></p> <p><em><strong>Helen Baker is a licensed Australian financial adviser and author of On Your Own Two Feet: The Essential Guide to Financial Independence for all Women. Helen is among the 1% of financial planners who hold a master’s degree in the field.

Homeowners often feel better about life than renters, but not always – whether you are mortgaged matters

<p><a href="https://theconversation.com/profiles/rachel-ong-viforj-113482">Rachel Ong ViforJ</a>, <em><a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em>; <a href="https://theconversation.com/profiles/hiroaki-suenaga-1477343">Hiroaki Suenaga</a>, <em><a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em>, and <a href="https://theconversation.com/profiles/ryan-brierty-1477346">Ryan Brierty</a>, <em><a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>Homeownership has long been thought of as the <a href="https://www.abc.net.au/news/2017-08-23/why-australians-are-obsessed-with-owning-property/8830976">great Australian dream</a>. For individuals, it’s seen as the path to adulthood and prosperity. For the nation, it’s seen as a cornerstone of economic and social policy.</p> <p>Implicit in this is the assumption that owning a home rather than renting one makes people better off.</p> <p>It’s an assumption we are now able to examine using data from the government-funded <a href="https://melbourneinstitute.unimelb.edu.au/hilda">Household, Income and Labour Dynamics in Australia</a> (HILDA) survey, which for two decades has asked questions both about homeownership and satisfaction with life.</p> <p>The <a href="https://melbourneinstitute.unimelb.edu.au/__data/assets/pdf_file/0007/4694137/ContinuingPersonQuestionnaireW23M.pdf">overarching question</a> asks "all things considered, how satisfied are you with your life? Pick a number between 0 and 10 to indicate how satisfied you are".</p> <p>We also looked at people’s satisfaction with their financial situation, their home and the neighbourhood in which they live.</p> <p>In a study published in the journal <a href="https://journals.sagepub.com/doi/10.1177/00420980231190479">Urban Studies</a>, we linked those answers to home ownership and characteristics including age and income.</p> <p>As expected, we found homeowners were generally more satisfied with their lives than renters. But we also find the extent to which they were more satisfied depended on whether or not they were still paying off a mortgage.</p> <h2>Mortgaged homeowners about as satisfied as renters</h2> <p>Outright home owners were 1.5 times as likely to report high overall satisfaction as renters. But home owners still paying off a mortgage were only a little more likely to feel high overall satisfaction.</p> <p>Similarly, outright owners were 2.3 times as likely to report high financial satisfaction as renters – but mortgaged owners were only 1.1 times as likely.</p> <p>When it comes to satisfaction with their home and neighbourhood, the differences were less extreme.</p> <p>Outright home owners were 3.1 times as likely to report high satisfaction with their home as renters, while mortgaged owners were 2.8 times as likely.</p> <p>Outright owners were 1.6 times as likely to report high satisfaction with their neighbourhood as renters, and mortgaged owners 1.4 times as likely.</p> <p>The results also varied with age and income.</p> <hr /> <p><iframe id="hK9Ua" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/hK9Ua/3/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>As shown in the graph above, outright owners were more likely to report high financial satisfaction than renters across almost the entire age range.</p> <p>But mortgaged owners only showed a demonstrably greater financial satisfaction than renters between the ages of 25 and 50.</p> <p>Beyond age 50, the existence of a mortgage debt burden appeared to cancel out any boost to financial satisfaction from homeownership. This potentially reflects the growing financial stress of making mortgage payments as retirement approaches.</p> <hr /> <p><iframe id="f2GSl" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/f2GSl/3/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>By income, mortgaged owners reported experiencing more financial satisfaction compared to renters the more they earned between A$80,000 and A$240,000. Outright owners experienced more financial satisfaction than renters up to A$320,000.</p> <p>Beyond these income levels, owners did not have greater financial satisfaction than renters, perhaps because high-earning renters have other sources of financial satisfaction.</p> <h2>How satisfied people feel beyond 60</h2> <p>In other respects, outright owners and mortgaged homeowners showed similar patterns, becoming more satisfied with their homes relative to renters the more they age up – until the age of 60. That’s when their satisfaction relative to renters declined, as illustrated below.</p> <p>This decline might reflect the growing physical burden of maintaining an owned home as people age.</p> <hr /> <p><iframe id="oLrHz" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/oLrHz/2/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>Our study has important implications. One is that age matters.</p> <p>Although older people consistently express a desire to <a href="https://www.ahuri.edu.au/analysis/brief/whats-needed-make-ageing-place-work-older-australians">age in place</a>, we found satisfaction among those who owned vs rented their home declined beyond age 60. This suggests better integration between housing and care is critical to support people ageing in place.</p> <p>Another implication is that as low-income owners are more reliant on their homes as a source of relative financial satisfaction than high earners, they are <a href="https://www.cambridge.org/core/journals/journal-of-social-policy/article/housing-equity-withdrawal-perceptions-of-obstacles-among-older-australian-home-owners-and-associated-service-providers/268F54A8EAA1E9ECA118E243505AA9FD">more exposed</a> in times of crisis. They may face the risk of being forced to sell suddenly with little time to consider the consequences.</p> <p>And another implication is as the relative financial satisfaction of mortgage holders disappears after the age of 50, and as more of us approach retirement with mortgages intact, more of us will either <a href="https://journals.sagepub.com/doi/10.1177/00420980211026578">postpone retirement</a> or become dissatisfied.</p> <p>Our findings suggest the extension of mortgage debt into later life should be discouraged if the benefits of the Australian dream are to be preserved.<!-- Below is The Conversation's page counter tag.

Does it matter what time of day I eat? And can intermittent fasting improve my health? Here’s what the science says

<p><em><a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/meltem-weger-1408599">Meltem Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Early hunter-gatherers faced long periods of fasting. Their <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">access to food</a> relied on successful hunting, fishing, and the availability of wild plants.</p> <p>Over time, the development of modern agriculture and the transition to industrialised societies <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">changed our regular eating patterns</a>, shifting our dinner time to later in the day to accommodate work schedules.</p> <p>Today, with access to an abundance of food, we rarely experience prolonged periods of fasting, except for weight loss or religious practices. It’s <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">now common</a> to have four or more meals a day, with the most calories consumed later in the day. Frequent snacking is also common, over a window of around 15 hours.</p> <p>However, research increasingly shows our health is not only affected by what and how much we eat, but also <em>when</em> we eat. So what does this mean for meal scheduling? And can intermittent fasting help?</p> <h2>Our body clock controls more than our sleep</h2> <p>Our internal biological timekeeper, or circadian clock, regulates many aspects of our physiology and behaviour. It tells us to be awake and active during the day, and <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">rest and sleep</a> during the night. It can also tell us the best time to eat.</p> <p>Our body is biologically prepared to have food during the day. Food digestion, nutrient uptake and energy metabolism is optimised to occur when we’re supposed to be active and eating.</p> <p>Working against this default stage, by regularly eating when we’re supposed to sleep and fast, can compromise these processes and impact our health. <a href="https://pubmed.ncbi.nlm.nih.gov/31813351/">Erratic eating patterns</a>, including late-night meals, have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/36198293/">weight gain</a> and a greater risk of metabolic disease.</p> <p>Shift-workers, for example, and people who work evening, night or rotating shifts, have a <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">higher risk</a> of obesity, heart disease and diabetes.</p> <p>But adopting an eating pattern that aligns with our circadian rhythm can reduce these risks.</p> <h2>So can intermittent fasting help?</h2> <p>Nutritional interventions are increasingly focused not only on “what” we eat but also “when”. Intermittent fasting is one way to restrict the timing, rather than the content, of what we eat.</p> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">several types</a> of intermittent fasting, one of which is time-restricted eating. This means eating all our calories in a consistent 8-12 hour, or even shorter, interval each day.</p> <p>But is it backed by evidence?</p> <p>Most of what we know today about intermittent fasting and time-restricted eating is from <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">mouse studies</a>, which demonstrate remarkable weight loss and overall health benefits associated with these types of dietary interventions.</p> <p>However, some aspects of mouse physiology can be different to humans. Mice need to eat more frequently than humans and even a short period of fasting has a more significant physiological impact on mice.

Embrace grey hair with our simple healthy hair tips

<p>While in the past going grey may have been seen as a negative of the ageing process, today women are embracing this as a stamp of wisdom. And why not? It’s en vogue and can look really attractive too. Thank goodness the days of “having” to hide your natural colour are gone! But just because you’re going natural, doesn’t mean there’s no effort involved. Knowing how to care for and style your grey locks is key and can make all the difference between “stylish and sixty-plus” and “stuffy and sixty-plus”. Read on for our top tips and tricks for healthy, happy hair.</p> <p><strong>Focus on your cut</strong> – A great cut is essential for any hair colour but especially for grey hair. Chances are good that you may have been dyeing your hair in the months/years leading up to embracing grey… so a decent chop may increase the health and vitality of your locks. Speak to your hairdresser about a style that suits both your face shape and lifestyle.</p> <p><strong>Swap your shampoo</strong> – Grey hair is far more prone to breakage and can also become quite dry and coarse. Ensuring that you’re using a moisturising shampoo at every wash can help keep strands in good condition.</p> <p><strong>Condition well</strong> – If you’ve been wary of conditioner in the past due to your hair being on the oily side, now is the time to become friendly again. Conditioning with a moisturising formula is essential after every shampoo. If you’re still nervous about hair becoming oily, you can try a shampoo for “normal” hair, which will nourish without weighing hair down.</p> <p><strong>Treat yourself to an at-home treatment</strong> – Once a fortnight, treat your hair with a shampoo specifically formulated for grey hair. After washing and conditioning, apply a clear colour glaze or gloss which is designed to coat the cuticle, boosting shine and general vitality.</p> <p><strong>Take care when styling</strong> – As it’s prone to dryness and breakage, applying a thermal protectant to your hair before heat styling is a great way to prevent damage from occurring. Simply comb through hair and style as normal. It’s also a good idea to try and have a day or two off a week from using your hairdryer/hot implements to give hair a good break.</p> <p><em>Images: Getty</em></p>

10 best tips for gracefully growing out grey hair

<h2>Pro tips that make going grey so much better</h2> <p>There’s no avoiding it. At some point, you will have to deal with grey hair. Of course, how you deal with it is up to you. Some women start growing out grey hair as soon as it begins to appear. Others begin their journey by pulling out greys and then spend years dyeing it before deciding it’s too much of a hassle to do the constant cover-up. Even if you’ve found the <a href="https://www.readersdigest.com.au/healthsmart/beauty/how-to-find-the-best-hair-colour-for-your-skin-tone" target="_blank" rel="noopener">best hair colour for your skin tone</a>, having to touch up your roots every four to six weeks can get old. No matter what your path is, going grey isn’t for the faint of heart.</p> <p>“Many women find it challenging to grow out grey hair,” says hairstylist Krysta Biancone. “This is because it usually occurs gradually, so the transition from natural hair colour to grey hair is not easy.”</p> <p>But it’s not all doom and gloom when it comes to going grey. In fact, it can be incredibly empowering, liberating and downright gorgeous when you make it to the finish line, and it can even make you look younger. But first, there are a few things you need to know. We asked top hairstylists around the country to divulge their best tips for making this transition as easy as possible.</p> <h2>Add highlights</h2> <p>It might sound counterintuitive, but adding subtle colour can make the transition to grey more seamless. “When you first decide you’re nearly ready to go natural, a step in the right direction would be to start going lighter. That way, the roots grow in a little more gracefully,” says hair stylist and colourist, Kali Ferrara. “This can be done easily by a skilled colourist, with a lighter base colour in conjunction with highlights.”</p> <p>One word of warning: steer clear of warmer colours like reds and strawberry blondes when growing out grey hair. Ferrara says these hues could backfire and show even more contrast with your roots.</p> <h2>Go a little darker</h2> <p>On the flip side, you could choose lowlights. But instead of adding a shade that’s slightly darker (which is normally what you’d do with lowlights), try to match your non-grey hair colour. This will help blend without adding a brand-new shade to the mix. “Lowlights create some contrast and will give hair a more salt-and-pepper look that can be very becoming,” says celebrity hairstylist Gina Rivera. Just be sure not to go darker than your hair colour, says Rivera. Doing so can create too much contrast and bring more attention to the fact that you are transitioning to grey, which won’t look good in photos or in real life.</p> <h2>Chop it off</h2> <p>Ready for a big change? Ferrara recommends growing your roots as long as you possibly can and then getting a super-short haircut to get rid of all the leftover colour. How short you go is totally up to you. A pixie cut can be chic and low-maintenance, but if you’ve never had short hair, that could be too big of a change. A short bob looks good on just about anyone, so that may be your best bet, though a stylist will be able to help you determine just how short will be flattering for your face shape. In general, slimmer faces tend to look great with hair that hits just under the jawbone, while fuller faces may want to go slightly longer (think a few centimetres below the jaw).</p> <p>“While this can be a dramatic change, it can also be just the new look you may be looking for!” Ferrara says. “Think of your natural hair colour as a new adventure – a new, liberated you.”</p> <h2>Cover roots as they grow in</h2> <p>If you’re growing out grey hair but your roots are driving you nuts, there are a few ways you can hide them. One easy solution is to cover them with a headband, hat or chic scarf. Another option is root spray or powder. “These products can mask the roots very effectively,” says master stylist Lorrene Conino. “Just spray the exposed areas after you style your hair.”</p> <p>Just shake the bottle well, hold it about 15 centimetres from your roots and spritz it on. These products offer instant coverage on grey hair without an expensive trip to the salon.</p> <h2>Don’t slack on trims</h2> <p>If you can’t bring yourself to do a big cut, regular haircuts (even little ones!) can help make the process go faster too. Aim for a trim every six to eight weeks. This will help you get rid of split ends and maintain healthy hair during your growing-out period, says hairstylist Nia Jones. After all, she explains, you may as well keep your hair looking as good as possible as you go through this tricky transition. Another bonus? Even if you aren’t getting a drastic cut, snipping a bit each time will get rid of old colour.</p> <h2>Prevent brassiness</h2> <p>As more and more grey starts growing in, make sure those strands look as good as possible. Although grey hair is less vibrant than hair of other colours, it still can become dull and uneven if not properly cared for. Sun exposure, washing hair with water that has a high mineral content, and improper hair care are just a few reasons grey locks can turn brassy. Luckily, there’s a quick fix: using shampoo and conditioner designed specifically for silver or white hair can help tone down brassiness by balancing out the warm undertones, says Biancone.</p> <p>You can also include purple toning products into your maintenance routine. Why purple? To understand how a purple product works, you need to know a bit about colour theory. Essentially, on the colour wheel, purple is opposite of yellow. This means that purple shampoo or toner helps to neutralise unwanted yellow or brassy tones that can come along with greys. Try adding toning drops to your shampoo or conditioner once a week to keep your hair the colour you want it. Taking this small precaution when caring for grey hair can help create luscious-looking locks with longevity.</p> <h2>Go big on moisture</h2> <p>The texture of grey hair is quite different from the hair of your youth. George Papanikolas, a celebrity hairstylist, explains that it’s typically more coarse, frizzy and dehydrated. To combat this, he recommends arming your strands with moisturising products that will keep it silky and shiny.</p> <h2>Don’t try to remove hair dye on your own</h2> <p>Let’s say you’ve been dying your hair to cover up those greys but wish you hadn’t. Well, even if you’ve just been using root touch-up kits as new greys grow in, you should never try to lift or remove hair dye on your own. “Chemicals are typically used to remove colour, and you need to know what you are doing,” warns Rivera. “If you don’t, you could end up really damaging your hair.” If this is a route you’re intent on exploring instead of waiting for the colour to grow out, book an appointment with a professional. Just be aware that removing hair dye is tricky and often takes multiple appointments.</p> <p>For an easier, much gentler option, try using a clarifying shampoo to lighten the dye on your strands, says Jones. These shampoos are formulated to remove excess buildup and give you a deep clean, but they may also help wash away some colour. Just don’t use them more than once a week. These products give hair a deep clean, and using them too often can strip your strands of natural oils that add hydration.</p> <h2>Experiment with new styles</h2> <p>Whether you’re trying to cover up the grey or want to embrace it, Jones suggests playing with different styles outside of the boundaries of your everyday look – ie, a ponytail, a different part that flatters your face shape or a brushed-back style that ‘hides’ roots. Changing things up allows you to play with your style, and it also makes growing out grey hair look cool and intentional. Who says blondes have all the fun?!</p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/beauty/10-best-tips-for-gracefully-growing-out-grey-hair" target="_blank" rel="noopener">Reader's Digest</a>.</em></p> <p><em>Images: Getty</em></p>

Unlocking the Silver Revolution: The Truth About Grey Hair and the Empowering Journey to Embrace the Grey

<p>In a recent poll by midlife connection organisation, Connected Women reveals that two-thirds of women over the age of 50 haven’t embraced their grey hair (67%). With hair starting to go grey in our 30s and 40s, that’s a long time to hide those pesky greys!</p> <p><strong>What causes grey hair? </strong></p> <p>According to Harvard Health, hair doesn’t ‘turn’ grey. Once a strand of hair is a particular colour, it will stay that way unless it is dyed. After the age of 35, hair follicles produce less colour, so when that strand of hair falls out it will be more likely to grow back grey.</p> <p><strong>Can stress cause grey hair? </strong></p> <p>There is very little evidence to indicate that this is true, however, research shows that in mice, in response to a fight or flight situation, hair follicles are impacted and the pigmentation-producing stem cells can be lost. Without stem cells available to produce pigment cells, the hair will go grey.</p> <p>So, can we now legitimately blame our grey hairs on our kids, or our husbands.</p> <p><strong>What happens when you pluck your grey hairs out? </strong></p> <p>Don’t do it! Not only will it simply grow back grey, but according to Trey Gillen, hairstylist and creative director of education at SACHAJUAN, doing so can also traumatise the follicles which could mean NO hair grows back.</p> <p><strong>When is the right time to go grey?</strong></p> <p>This is something that only you can decide. If your hair is dark brown or black, your greys will be more noticeable, so you’ll need to have regular (two to four weekly) trips to the hairdresser to cover them up. At some point you will most likely grow weary of trying to stem the tide and it will be time to just embrace the grey. You will know when you’ve had enough!</p> <p>If you have lighter hair, then your greys will be much less noticeable. Lighter hair gives you a much longer window between coloring appointments in the initial stages of going grey, and later you can use the greys as ‘herringbone highlights’ as per Sarah Jessica Parker’s beautiful mane, which is wonderful way to gracefully embrace going grey.</p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2023/05/Phoebe-headshot-EDITED.jpg" alt="" width="1280" height="720" /></p> <p><span style="box-sizing: border-box; font-weight: bolder; color: #212529; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px; background-color: #ffffff;"><span style="box-sizing: border-box; caret-color: #212529;"><em style="box-sizing: border-box;">Phoebe Adams is the founder of Connected Women, an organisation providing a community for women over 50 to connect with each other and build meaningful friendships.

The legal matters you need to consider as you get older

<p><em><strong>Barbara Binland is the pen name of a senior, Julie Grenness, in Melbourne, Victoria, Australia. She is a poet, writer, and part-time English and Maths tutor, with over 40 years of experience. Her many books are available on Amazon and Kindle.</strong></em></p> <p>As we are ageing, it is essential at some stage to be realistic and sort our legal affairs. This incorporates writing your last will and testament. It is an individual’s choice whether to use a will kit, or to engage a solicitor. We must decide on an executor of the will, to ensure any assets are disposed of, in accordance with our intentions.</p> <p>Secondly, it is an excellent idea to appoint a medical power of attorney to a trusted person, to factor in a case scenario if you are on life support. Someone needs a medical power of attorney to make tough decisions on your behalf.</p> <p>Thirdly, when writing your will, you need to list your beneficiaries. Moreover, you need to compile a file of your assets and investments. Furthermore, it is also a good intention to prepare any wishes for your funeral, burial or cremation. Do you wish to be an organ donor? Ultimately, if any doubts occur, it is always possible and feasible to seek advice from any legal professionals.</p> <p>Right, having done all that, it’s easy to think, “all sorted!” But remember, any golden oldie’s status can be affected by any change in circumstance, such as either health conditions, or by marriage, or divorce, or the death of a spouse. Then we may need to revise our will and testament.</p> <p>But, in the interim, put morbid thoughts to one side, that is all ‘worst case scenario’. Now we can plan for our happy and leisurely retirement, enjoying being ‘golden oldies’, anyway we choose!</p> <p>Here are the stats: 10/10 people are going to die, so appreciate being alive! Rise and smile!</p> <p><em>Image credit: Shutterstock</em></p>

I’ve indulged over the holidays. If I’m healthy the rest of the time, does it matter?

<p>The holidays are often called the “silly season” – a time when we eat, drink and be merry. But these holiday indulgences can lead to feelings of guilt and fear that we’ve undone all the healthy habits from the rest of the year. But how much do you really need to worry about the impacts of holiday overeating?</p> <h2>Yes, weight gain can happen in the holidays</h2> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/31953670/">studies</a> that show weight gain can and does occur in the silly season. But on average it’s not as dramatic as diet culture would have us believe, coming in at about 0.7kg.</p> <p>However, because humans are complex and varied, and nutrition science is hard, there are studies with varied findings. Some show that despite significant increases in <a href="https://pubmed.ncbi.nlm.nih.gov/32203107/">overall energy intake</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/27618574/">reductions in diet quality</a>, <a href="https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=1300&amp;context=etd">weight gain doesn’t occur</a>. </p> <p>Importantly, much of this research comes from the northern hemisphere where the major holidays coincide with winter. And these studies focus on weight, not health. Weight is just a marker that’s convenient to measure, but <a href="https://nutritionj.biomedcentral.com/articles/10.1186/1475-2891-10-9">health is more complicated</a>.</p> <h2>Food is not just fuel</h2> <p>Food isn’t just energy and nutrients. It’s a big part of our cultures and celebrations, and contributes to <a href="https://www.tandfonline.com/doi/abs/10.1300/J140v06n04_04?casa_token=B88qy23WbRMAAAAA:HbizzLaYk_SDbucI00WWrJ1krwp5lZFgJjDpFBs6CkbkEXHEbfVhPfbH9uUooPh0z5ay3vLkKRJ-di8">social, cultural and emotional wellbeing</a>.</p> <p>While it’s harder to study, nourishing our souls with foods that connect us to our loved ones and our traditions is just as important as the role food plays in nourishing our bodies.</p> <p>Holiday feasts are also an opportunity to share meals. Sharing meals <a href="https://link.springer.com/article/10.1007/s40750-017-0061-4">contributes to our emotional wellbeing and happiness</a>.</p> <h2>Say hello to homeostasis</h2> <p><a href="https://www.britannica.com/science/homeostasis">Homeostasis</a> is a scientific term that describes how systems self-regulate. The word comes from the ancient Greek words for “similar” and “steady”. </p> <p>In living things it means that biology can adapt to changes to keep things in their normal constant state. Essentially, our body is always making little constant biological changes to help things stay the same. This is how we regulate things like our body temperature, blood sugar, blood pressure and other systems important for survival. </p> <p>The principles of homeostasis also apply to our <a href="https://www.frontiersin.org/articles/10.3389/fphys.2021.658997/full">eating and metabolism</a>. If we eat more for one or two holiday feast days (or even weeks) our biology works to minimise the impacts. This is also why losing weight on restrictive diets can be hard – homeostasis means as we reduce our energy intake our bodies adjust to using less energy. </p> <p>So for most people, discrete periods of indulgence aren’t likely to be the major determinants of health outcomes. It’s more likely the patterns we follow most of the time will influence our long term health.</p> <h2>It’s about balance</h2> <p>Biology and social norms both mean restrictive diets are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7538029/">hard to maintain long-term</a>. Some people are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0148296321002940">more successful</a> in maintaining a balanced diet when indulging is allowed. </p> <p>And now science has helped you to relax a little, a few words of caution.</p> <h2>Drink in moderation</h2> <p>Over-consumption of alcohol can cause <a href="https://www.cdc.gov/alcohol/fact-sheets/alcohol-use.htm#:%7E:text=Over%20time%2C%20excessive%20alcohol%20use,liver%20disease%2C%20and%20digestive%20problems.&amp;text=Cancer%20of%20the%20breast%2C%20mouth,liver%2C%20colon%2C%20and%20rectum.">increased risk for chronic diseases</a>. </p> <p>Excess alcohol consumption in the festive period increases the risk of alcohol-related harm, <a href="https://www.vichealth.vic.gov.au/-/media/ResourceCentre/PublicationsandResources/alcohol-misuse/Drinking-cultures-social-occasions-Factsheet_public-holiday.pdf?la=en&amp;hash=6C43A7F27769C7016FBBC0C1AA35CA3FC74A7A0C">including accidents and violence</a>. </p> <p>Staying hydrated by alternating with non-alcoholic beverages helps reduce how much you drink and how bad a hangover is, but it won’t eliminate the risks.</p> <h2>Food safety risks</h2> <p>Festive eating, with sharing, travelling and over-crowded fridges increases our <a href="https://www.cdc.gov/foodsafety/communication/holidays.html">risks of food poisoning</a>. Summer holidays also bring the added risk of heat. </p> <p>You want to share food and joy, not germs, so remember your <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/food-poisoning-prevention">basic food safety rules</a> like hand washing, avoiding cross contamination of uncooked meats and other foods, storing food chilled, and heating thoroughly. </p> <p>It’s also a good idea to make sure you talk to your guests or hosts about food allergens to make sure everyone has a safe holiday feast. </p> <h2>The bottom line</h2> <p>What we eat is a big part of determining our health, but adding a side serving of guilt to your festive feast isn’t healthy either. </p> <p>For true healthy choices, focus on balance and moderation for the bulk of the year and for most of your choices, but social and cultural eating is part of balance.</p> <p>Enjoying your celebration foods doesn’t need to mean throwing away all your healthy habits, but healthy eating and healthy indulgence can co-exist if we let it.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/ive-indulged-over-the-holidays-if-im-healthy-the-rest-of-the-time-does-it-matter-195643" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Explainer: Why does hair turn grey?

<p>For many people, grey hair is a fact of life. It’s a sign that we are getting older and that our bodies are going through change. </p> <p>To understand why hair turns grey, we first need to understand why it has colour in the first place. The answer is a special type of cell known as a melanocyte. These produce melanin, the pigment that gives your skin, hair and eyes their distinctive colours.</p> <p>Melanin comes in two forms, eumelanin (black or brown) and pheomelanin (reddish-yellow). Combinations of these two create the spectrum of eye, hair and skin colours found among humans.</p> <p>One way to understand how melanocytes determine hair colour is to think of these cells as tiny printers, applying their ink to paper. The paper in this case is our hair strands, formed of keratin, the same protein that makes up our fingernails.</p> <p>Just as a printer sprays ink onto a sheet of paper to produce an image, melanocytes produce pigments that are embedded into the growing hair strand, providing them with colour. The melanocytes live within the hair follicle, so each hair strand has its own colour-producing printer.</p> <p>While some people’s melanocytes print a lighter ink combination, such as blonde or red, others have darker colour palletes and so have black or brown colourations.</p> <p>Now that we understand how hair gets its colour, we can understand why it goes grey.</p> <p>In hair, grey is not a colouration like any other shade: it is the lack of colouring. The keratin of people with grey hair lacks pigment because their melanocytes have died, revealing the natural grey-white colour of the keratin protein.</p> <p>Because each hair strand has its own melanocytes, some go grey before others. Exactly what decides which strands go grey first is still unknown. However, age, exposure to chemicals and even the climate can influence how early the melanocytes die.</p> <p>The strongest influence, however, is written in our genes. The genetic influence on hair colour is so strong that if your parents have grey hair, yours is likely to grey at around the same time as theirs did.</p> <p><em>Image credits: Getty Images</em></p> <p><em><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=19408&amp;title=Explainer%3A+Why+does+hair+turn+grey%3F" width="1" height="1" /></em></p> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/science/biology/explainer-why-does-hair-turn-grey/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Jake Port. </em></p> </div>

Glute force: why big, strong bum muscles matter for your overall health

<p>The glutes are the large, powerful muscles in your bum that help support the pelvis, stabilise the hip joint and allow the hip to move.</p> <p>Countless social media posts extol the virtues of building strong glutes through exercises such as squats. However, most of what you hear from such “gymfluencers” is about how the bum muscles look.</p> <p>Forget about how they look; what about what they do? Why is having big, strong glutes important for your body to function well?</p> <p>In fact, having strong bum muscles is crucial to good musculoskeletal health.</p> <h2>Bum muscles hold your body up and protect the hip joint</h2> <p>The gluteal muscles are a group of three separate muscles, each with unique anatomical structure and function.</p> <p>The deepest and smallest muscle is called the gluteus minimus, which is very close to the hip joint itself.</p> <p>Overlaying gluteus minimus is the gluteus medius. This one is relatively large and spans the whole outer surface of the pelvis.</p> <p>The gluteus maximus is the largest of the three gluteal muscles and <a href="https://pubmed.ncbi.nlm.nih.gov/19449297/" target="_blank" rel="noopener">overlays</a> both gluteus medius and minimus. This muscle is what gives the the bum its distinctive bum-like shape, but it plays a very important role in the way your body functions.</p> <p>In combination, the gluteus maximus, medius and minimus gives rise to many hip movements, and provide shock absorption when you’re walking or running.</p> <p>These muscles work together with your brain to generate a lot of power to hold your body up as gravity tries to pull it down. They also protect the hip joint from impact and from shearing forces that might cause long term damage.</p> <p>Some of <a href="https://onlinelibrary.wiley.com/doi/10.1002/ca.23510">our</a> <a href="https://www.sciencedirect.com/science/article/pii/S1063458418315127?via%3Dihub">work</a> has identified some people with hip pain also have impairments in the gluteal muscles.</p> <p>These impairments could reduce the bum muscles’ ability to protect the joint against long term damage and potentially affect a person’s ability to bear weight (for example, when standing on one leg or climbing stairs).</p> <p>A reduction in muscle size and an increase in non-active tissue such as fat has been <a href="https://pubmed.ncbi.nlm.nih.gov/31689358/" target="_blank" rel="noopener">reported</a> in hip conditions such as greater trochanteric pain syndrome (a common type of hip pain, also known as gluteal tendinopathy).</p> <p>The same is also true for <a href="https://www.oarsijournal.com/article/S1063-4584(16)30064-4/fulltext" target="_blank" rel="noopener">hip osteoarthritis</a>, which affects the whole joint.</p> <p>The rates of osteoarthritis in Australia are <a href="https://doi.org/10.1111/imj.15933" target="_blank" rel="noopener">increasing</a>, with <a href="https://aoj.amegroups.com/article/view/3664/4322" target="_blank" rel="noopener">one in every seven</a> hip joint replacements conducted in people under the age of 55.

Democracy spreads in waves – but shared cultural history might matter more than geography

<p>Recent events like the war in Ukraine, conflicts over Taiwan and the rise of authoritarian ideology have renewed interest in the foundations of modern democracy.</p> <p>They have raised questions about why some nations are more democratic than others, and how democratic institutions, freedoms and values are spread or lost.</p> <p>We tend to think of this variation in terms of geography – democratic Western Europe or autocratic Middle East.</p> <p>But in a <a href="https://www.cambridge.org/core/journals/evolutionary-human-sciences/article/shared-cultural-ancestry-predicts-the-global-diffusion-of-democracy/90C7A170B924FC305DD66FF8853799FC" target="_blank" rel="noopener">new analysis of 220 years of political data</a>, we show that deep cultural connections between countries such as shared linguistic or religious ancestry matter more than geography.</p> <h2>Waves of democratisation</h2> <p>The emergence of modern democracy coincides with the rise of nation states in Europe at the beginning of the 19th century. Democracy spread across European nations and their colonies, over <a href="https://en.wikipedia.org/wiki/The_Third_Wave:_Democratization_in_the_Late_Twentieth_Century" target="_blank" rel="noopener">three waves</a>.</p> <p>The first wave lasted about a century, from 1828 to 1926, halting after the first world war. A second, rapid wave (1945-1962) followed the second world war and decolonisation.</p> <p>The third wave began in 1974 and continues today. It encompassed political transitions and new countries in Europe, Latin America and the Pacific.</p> <p>Each wave was followed by a period of reversals when nations turned to autocratic regimes, junta or fascism. Indeed, some researchers speculate we are heading into <a href="https://www.tandfonline.com/doi/full/10.1080/13510347.2019.1582029" target="_blank" rel="noopener">another period of reversal</a>.</p> <h2>What drives modern democracy?</h2> <p>Scholars traditionally considered factors internal to a country – economic growth, rates of education or the natural environment – as the drivers of these waves. However, the geographic clustering of democracy and the wave-like pattern of expansion suggest the process may also involve a kind of contagion where democracy passes from one nation to another.</p> <p>One explanation for this is that democratic change spreads across borders, so that neighbouring countries end up with similar levels of democracy.</p> <p>Culture provides another explanation. Neighbouring countries tend to share a common cultural heritage, such as related languages or religions. This shapes national institutions, norms and values.</p> <p>In our research, we tested the idea that common cultural ancestry explains variation and change in democracy around the globe. We brought together 220 years of democracy data with information on the cultural relationships between nations. The cultural relationships we examined were based on languages and religious beliefs.</p> <p>For example, Portugal is linguistically closer to Spanish-speaking Argentina and Spain than to England and Germany (which speak Germanic languages). Likewise, Myanmar, a Theravada Buddhist country, is religiously closer to Mongolia (where Vajrayana Buddhism is predominant) than to Muslim Malaysia.</p> <h2>Culture is more important than geography</h2> <p>The democracy data we studied cover 269 modern and historical nations and three widely-used democracy indicators, measuring democratic and autocratic authority in governing institutions (<a href="https://www.systemicpeace.org/polityproject.html" target="_blank" rel="noopener">Polity 5</a>), electoral participation and competition (<a href="https://www.prio.org/data/20" target="_blank" rel="noopener">Vanhanen Index</a>) and individual rights and freedoms (<a href="https://freedomhouse.org/" target="_blank" rel="noopener">Freedom House</a>).</p> <p>Across all three indicators of democracy, we found countries that share linguistic or religious ancestry tend to have more similar democracy scores. These shared cultural ties were better predictors of democracy than geography, especially during the third wave of democratisation.</p> <p>Knowing the democratic status of a country’s linguistic or religious relatives helps predict that country’s future level of democracy five, ten or even 20 years later.</p> <p>These effects were not just due to countries sharing a language (for example, the English-speaking world) or religion (such as the Sunni Islam majority countries). This suggests deeper cultural connections between countries are important.</p> <h2>What this means for the spread of democracy</h2> <p>These effects could be the result of a number of processes.</p> <p>One possibility is that countries directly inherited institutions along the same pathways they inherited cultural features like language. For instance, Aotearoa New Zealand and other Commonwealth countries inherited the British legal system along with the English language.</p> <p>Another possibility is that cultural similarities might make countries more likely to maintain ongoing social connections, including foreign relations, which then aid the spread of institutions. For example, the <a href="https://theconversation.com/how-the-arab-spring-changed-the-middle-east-and-north-africa-forever-161394" target="_blank" rel="noopener">Arab Spring</a> spread among a set of countries with common linguistic and religious heritage.</p> <p>A third possibility is that inherited cultural values could steer countries towards similar institutions. For example, <a href="https://www.nature.com/articles/s41562-019-0769-1" target="_blank" rel="noopener">in previous research</a> we found that tolerance of diversity (cosmopolitan values) promotes a shift to more democratic institutions, but the reverse is not true. Democratic institutions do not shift tolerance.</p> <p>Countries that have inherited cosmopolitan values as part of their shared cultural ancestry may be more likely to shift towards democracy. If this theory is correct, it calls into question the assumption that democratic institutions can endure without sustained efforts to promote the cultural values that support them. The US interventions in Afghanistan and Iraq may be tragic examples of this.</p> <p>Our findings indicate cultural history matters for understanding the spread of democracy around the globe. This does not mean culture is the only factor at play (our analyses still leave a lot of variation unexplained). Neither do our findings speak to a population’s ultimate potential to achieve democratic outcomes, but we see this as within the reach of all populations.</p> <p>This means those wishing to support democracy at home or abroad should take cultural barriers seriously. We cannot assume that institutions that work well in one cultural setting can be easily transplanted to another, very different setting, with different values, norms and traditions. We should pay more attention to culturally closely related countries that have succeeded at merging local norms and values with democratic institutions.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/democracy-spreads-in-waves-but-shared-cultural-history-might-matter-more-than-geography-189959" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

Why the size of your glasses matters

<p>It can be frustrating when you’ve picked up your news glasses only to find the frame presses against your head or the glasses keep slipping down your nose. Getting the right pair of glasses isn’t just about the right prescription, finding a comfortable frame is also key to enjoying relaxed and (almost) perfect vision. So if you’ve ever suffered buyer’s remorse after a glasses purchase, here are the tips to follow so you always get the perfect fit for your new glasses.</p> <p><strong>The lens</strong></p> <p>In general, the thinner and lighter the lens, the more comfortable the spectacles will be to wear. If possible, choose a thinner lens so your glasses won’t feel as heavy on the nose and ears.</p> <p><strong>The nose bridge</strong></p> <p>As one of the few points of contact with your face, it’s important to carefully consider the comfort of the glasses’ nose bridge. You want the nose pads to sit solidly on your nose, otherwise they can quickly lose their grip and keep sliding down.</p> <p><strong>The sides</strong></p> <p>The sides of your spectacles shouldn’t press into your temples. Some people mistakenly believe pressure means the glasses fit properly, but there should never be any heaviness felt on the temples. You might feel some pressure behind the ear, but that’s ok as this keeps the weight of the glasses from being borne wholly by your nose.</p> <p><strong>The frame</strong></p> <p>As a general rule, when you look through your glasses it should be at the middle of the lens. The top of the frame should sit below the eyebrows but above the fold of the eye and the frame should not be much wider than your face.</p> <p><em>Image: Getty Images</em></p>

Veteran newsreader reportedly fired for "going grey"

<p>A veteran newsreader has reportedly been fired from one of Canada’s most-watched television news programs after "going grey". </p> <p>Lisa LaFlamme announced she would be leaving the CTV National News presenter said she was “blindsided” and left “shocked and saddened” by the allegedly sudden decision to end her contract.</p> <p>“At 58, I still thought I’d have a lot more time to tell more of the stories that impact our daily lives,” she said in the Twitter video.</p> <p>“It is crushing to be leaving CTV National News in a manner that is not my choice.”</p> <p>The news anchor said she was asked to keep the details of her termination confidential, as the company released a statement saying the decision had nothing to do with LaFlamme’s hair colour or age and was simply “a business decision”.</p> <p>LaFlamme, like many people around the world, stopped dying her previously brown hair throughout the pandemic, a decision she told viewers she wished she had made sooner.</p> <p>“I finally said, ‘Why bother? I’m going grey.’ Honestly, if I had known the lockdown could be so liberating on that front I would have done it a lot sooner,” she said during the network’s year-in-review special.</p> <p>LaFlamme has been in the anchor job since 2011 but has been with the news outlet for 35 years, and still had two years left on her contract at the time of the “blindside”.</p> <p>Bell Media, which owns CTV National News, said it knew many viewers would be disappointed LaFlamme “would be leaving her position”, and regretted the way the news had been revealed.</p> <p>It added it would launch an independent investigation into newsroom practices.</p> <p>“CTV regrets that the way in which the news of her departure has been communicated may have left viewers with the wrong impression about how CTV regards Lisa and her remarkable career,” Bell Media tweeted in a statement.</p> <p>“We have always taken matters regarding any discrimination very seriously and are committed to a safe, inclusive and respectful work environment for all our employees, devoid of any toxic behaviour."</p> <p>“Consistent with our policies, we are taking steps to initiate an independent third-party internal workplace review of our newsroom, which will take place over the following weeks.”</p> <p><em>Image credits: CTV News</em></p>

For the love of Greys – retiree volunteers and retired ex-racers

<p>It’s an unexpected match made in heaven, but retirees hoping to give their time to a good cause could find one in a four-legged friend looking for a home.</p> <p>With National Volunteer Week (16 – 22 May 2022) soon upon us, it’s timely to recognise all volunteers. But there’s a very special group of retirees who go the extra mile for Greyhounds.</p> <p>Contrary to popular belief, Greyhounds are big goofy sooks and will swamp you with adoration and love. They’ll also adopt a place on your couch or bed as a loyal pet. This is why many volunteers and foster carers not only adopt a grey or two, but also actively want to save them from greyhound racing.</p> <p>Not surprisingly, the RSPCA <a href="https://kb.rspca.org.au/knowledge-base/what-are-the-animal-welfare-issues-with-greyhound-racing/#what-needs-to-change" target="_blank" rel="noopener">does not support greyhound racing</a> due to the many unresolved animal welfare concerns associated with the so-called sport. These concerns motivate rescue groups, as well as activists.</p> <p>CPG (the Coalition for the Protection of Greyhounds) is a dedicated group of volunteers across Australia who work together to inform the public about the cruelties of dog racing – <a href="http://www.facebook.com/CoalitionForTheProtectionOfGreyhounds" target="_blank" rel="noopener">FB</a>,<a href="http://www.greyhoundcoalition.com/" target="_blank" rel="noopener"> </a><a href="http://www.greyhoundcoalition.com/" target="_blank" rel="noopener">web</a>,<a href="https://www.instagram.com/coalitionprotectgreyhounds/" target="_blank" rel="noopener"> </a><a href="https://www.instagram.com/coalitionprotectgreyhounds/" target="_blank" rel="noopener">Insta</a>,<a href="http://www.greyhoundcoalition.com/cpg-in-the-media" target="_blank" rel="noopener"> </a><a href="http://www.greyhoundcoalition.com/cpg-in-the-media" target="_blank" rel="noopener">media coverage</a></p> <p>Retired nurse Annie is one of CPG’s amazingly enthusiastic volunteers. She’s a media spokesperson for the group and is often busy doing radio and newspaper interviews. Her love affair with Greyhounds started long ago.</p> <p>“I saw an ad on Facebook by Gumtree Greys for foster carers, applied and was introduced to Holly. This beautiful black greyhound girl had been an Irish Champion and ‘Bitch of the year’ in 2012. She was bought by an Australian syndicate at two years old and kept to breed from,” said Annie.</p> <p>Holly whelped many litters until she was nine years old and had her last puppies by caesarean. When Annie took Holly to be desexed, the vet said she was a mess inside and had been sewn up with nylon non-dissolving sutures.</p> <p>“Holly taught me all about how gentle, quirky, dorky, loving and unintentionally hilarious greyhounds are, like the way their jaws quiver when they are happy. All of my future foster greyhounds learnt how to become great pets with guidance from gorgeous Holly,” said Annie.</p> <p>“I foster greyhounds because they deserve the chance of a good life as a dog and pet, not just a product or commodity. Greyhounds bring me so much joy. In return, I speak out for them because of what they suffer on Australia’s many racing tracks.”</p> <p>Annie says she’s appalled by the fact that in 2021, there were <a href="https://greyhoundcoalition.com/2021-australian-track-deaths-and-injuries/" target="_blank" rel="noopener">212 greyhound deaths</a> on Australian dog tracks and over 10,000 injuries, according to statistics from official stewards’ reports. Because of this, she volunteers for CPG and other greyhound-related voluntary bodies. She’s also a motorbike enthusiast and uses her motorbike riding to raise money for greyhound welfare.</p> <p>Alicia – one of CPG’s newest volunteers – is semi-retired. She works part-time in journalism and interior design, but adores Greyhounds. Her male black Greyhound, Fluffy, is now nearly seven years old and has been retired from racing for four years.</p> <p>“Fluffy is one of the lucky survivors from the greyhound racing tracks, as he only won one race and is loving his retired life on the couch! He’s a soppy sook despite his size and the name suits him down to the ground as he is not an Anubis or Nero by nature,” said Alicia.</p> <p>“My lovely boy is very nervous due to his past racing days. He’s frightened of loud noises such as cars or motorbikes, as well as thunder and lightning. He absolutely loves children and babies, as he instinctively knows they won’t harm him.”</p> <p>She says greyhounds are ideal companions for retirees as they are lazy couch potatoes, love cuddles, are very affectionate and generally don’t need more than one walk of 20 minutes a day.</p> <p>“I volunteer with CPG by writing content for publication. They really need more people who have at least five years’ experience writing news releases and placing them with media outlets. Greyhounds are innocents with no voice, so we speak up for them,” said Alicia.</p> <p>She said CPG’s <a href="https://greyhoundcoalition.com/5-key-demands/" target="_blank" rel="noopener">five-point plan</a> is aimed at reforming the racing industry. As well as increased penalties for mistreatment, the plan includes tracking each dog from birth to death so they don’t ‘disappear’, reduced breeding, sanctuaries and safer tracks.</p> <p>Fran, previously a lecturer in Environmental Science, is spokesperson and leader of the Tasmanian activist group <a href="https://www.facebook.com/Let-Greyhounds-Run-Free-425546354301519/?ref=page_internal" target="_blank" rel="noopener">Let Greyhounds Run Free</a> (LGRF), which formed as a result of the ABC's Four Corners program on live baiting and the subsequent Parliamentary Inquiry into the Tasmanian Greyhound Industry. LGRF has held several rallies against greyhound racing, and continues to lobby for the end of this cruel, archaic industry. </p> <p>Fran began her greyhound journey back in 2000 when she came across a Greyhound Adoption stall at a local event. She was instantly hooked after meeting a few of these four-legged beauties and adopted the timid and scared Miss Ruby. It was Ruby who introduced Fran to the dark life of a racing greyhound. </p> <p>Ruby was soon joined by regal Jena. Ruby was terrified, and Jena was injured and a severe epileptic - why we may never know, and it was then that Fran vowed she would do whatever she could to end greyhound racing.</p> <p>All these years later, having had the joy of six hounds and several more foster hounds, she now has the privilege of living with Paddy and Jennifer Jane.</p> <p>Paddy became well known in promotions for Let Greyhounds Run Free's rallies. He is also a champion at helping timid and shy foster greyhounds come back to life after their traumas, and adjust to life as it should be, in a safe and loving home. </p> <p>“I have stories about all the beauties who have blessed my life. They are the most gentle, loving, soul-filled, quirky beings and I'm so very grateful I met ‘Miss Ruby Two Shoes’ way back then in 2000” says Fran. </p> <p>Meanwhile, retired lawyer Jeff is also a tireless campaigner, volunteer and lover of greyhounds. He’s been a supporter of the worldwide campaign to end greyhound racing for the last 15 years or so.</p> <p>“When my pet greyhound died in 2015, I promised myself to continue fighting for the cause. That was the year when the live baiting scandal broke in Australia,” he said.</p> <p>“I followed the news reports and the inquiries closely. When an opportunity arose to become an admin at the new Facebook group ‘<a href="https://www.facebook.com/groups/1376102522706650/" target="_blank" rel="noopener">Ban Greyhound Racing – Australia Wide</a>’, it was an ideal way to support the growing anti-racing campaign.”</p> <p>Jeff said the group’s focus has always been on activism.</p> <p>“There are many other social media outlets where people can share pictures of their rescued greyhounds and discuss their care, behaviour and feeding. On our page, we try to be a resource for current information about the Australian racing industry.”</p> <p>Those interested in adopting or fostering a goofy hound, should contact one of the groups listed <a href="https://greyhoundcoalition.com/links-to-greyhound-rescue-groups/" target="_blank" rel="noopener">here</a>, while anyone interested in volunteering with CPG, can find out more <a href="https://greyhoundcoalition.com/volunteering-with-cpg/" target="_blank" rel="noopener">here</a>. For further information about greyhound welfare issues, see CPG’s hot topics listed <a href="https://greyhoundcoalition.com/media-resource/" target="_blank" rel="noopener">here</a>.</p> <p style="margin-bottom: 7.95pt; line-height: 12.6pt;"><em>Images: Supplied</em></p>

Vandals of the UK’s Edward Colston statue learn their fate in court

<p><span style="font-weight: 400;">At the height of the Black Lives Matter protests in 2020, that were sparked by the murder of George Floyd by a US police officer, protestors all around the world took it upon themselves to remove commemorative statues of slave traders. </span></p> <p><span style="font-weight: 400;">In the UK city of Bristol, four people removed a monument of Edward Colston from a town square, before pushing the statue into the nearby harbour. </span></p> <p><span style="font-weight: 400;">Many protestors joined the four in spray-painting and destroying the statue, with many onlookers filming the destruction on their phones. </span></p> <p><span style="font-weight: 400;">Edward Colston was a member of the Royal African Company, and was responsible for transporting thousands of slaves from Africa during the mid 17th century. </span></p> <p><span style="font-weight: 400;">The four protestors - </span><span style="font-weight: 400;">Rhian Graham, Jake Skuse, Sage Willoughby, and Milo Ponsford - were all charged with criminal damage when they removed the statue without permission. </span></p> <p><span style="font-weight: 400;">According to the </span><a href="https://www.theguardian.com/uk-news/2022/jan/05/four-cleared-of-toppling-edward-colston-statute"><span style="font-weight: 400;">Guardian</span></a><span style="font-weight: 400;">, the protestors did not deny that they had toppled the monument, but maintained their innocence over the charges. </span></p> <p><span style="font-weight: 400;">Despite admitting their involvement, the four protestors were found not guilty and set free. </span></p> <p><span style="font-weight: 400;">The graffitied monument of Colston has since gone back on view in view in Bristol in a museum, with historian David Olusoga saying that it is “the most important artifact you could select in Britain if you wanted to tell the story of Britain’s tortuous relationship with its role in the Atlantic slave trade.”</span></p> <p><em><span style="font-weight: 400;">Image credits: Getty Images </span></em></p>

How efficient is the human brain?

<p><span style="font-size: 14px;">What is the difference between human brains and those of other mammals? Potentially, energy efficiency, according to a </span><a style="font-size: 14px;" rel="noopener" href="https://dx.doi.org/10.1038/s41586-021-04072-3" target="_blank">study</a><span style="font-size: 14px;">, published in </span><em style="font-size: 14px;">Nature.</em></p> <div class="copy"> <p>Neurons in the brain communicate with each other via electrical pulses. These pulses, generated as ions such as potassium and sodium, enter the cell through an ion channel. The channels act as an “on-off” switch by changing shape to alter the flow of the ions, either letting them in and generating an electrical signal, or closing to prevent the signal getting through.</p> <p>Now, a team of researchers from Massachusetts Institute of Technology have found that the number of ion channels in the human brain are at a lower density than in other mammals’ brains. They have hypothesised that this has helped human brains become more efficient.</p> <p>The researchers analysed neurons from 10 mammals – the most extensive electrophysical study of its kind to date – and found that bigger neurons lead to more ion channels in a relatively constant ratio of size-to-channels.</p> <p>What this means is that bigger neurons can still handle all the electrical pulses they are bombarded with because they have the ion channel capacity to process the ions. No matter the brain size, the energetic cost to run each mammal’s brain was about the same.</p> <p><strong>The human brain is the exception</strong></p> <p>That is, in every mammal except humans, who had a much lower density of ion channels than expected.</p> <p>“Previous comparative studies established that the human brain is built like other mammalian brains, so we were surprised to find strong evidence that human neurons are special,” says former MIT graduate student Lou Beaulieu-Laroche.</p> <p>Graphical abstract. Created on imgflip by Cosmos.</p> <p>One benefit of a lower density of ion channels may be that less energy is used on pumping ions into neurons, which could then be diverted to other processes, like creating more complicated synaptic connections.</p> <p>“If the brain can save energy by reducing the density of ion channels, it can spend that energy on other neuronal or circuit processes,” says Mark Harnett, an associate professor of brain and cognitive sciences, a member of MIT’s McGovern Institute for Brain Research, and the senior author of the study.</p> <p>“We think that humans have evolved out of this building plan that was previously restricting the size of cortex, and they figured out a way to become more energetically efficient, so you spend less [energy] per volume compared to other species.”</p> <p>In this case, the human brain could run on the same amount of power as other mammal brains but perform more complex procedures with the excess energy diverted from ion channels.</p> <p>Harnett hopes to study where that extra energy is being used and whether there are any specific genes responsible for ion channel density exclusive to humans.</p> <!-- Start of tracking content syndication.
