Stop Sabotaging Your Gut

This is Dr. Robynne Chutkan. She’s an integrative gastroenterologist, and founder of the Digestive Center for Wellness, in Washington DC, which for the past 20 years has been dedicated to uncovering the root causes of gastrointestinal disorders, while the therapeutic side of things has been focused on microbial optimization, nutritional therapy, mind-body techniques, and lifestyle changes.

In other words, maximal health for minimal medicalization.

So… What does she want us to know?

Live dirty

While attentive handwashing is important to avoid the spread of communicable diseases*, excessive cleanliness in general can result in an immune system that has no idea how to deal with pathogens when exposure does finally occur.

*See also: The Truth About Handwashing

This goes doubly for babies: especially those who were born by c-section and thus missed out on getting colonized by vaginal bacteria, and especially those who are not breast-fed, and thus miss out on nutrients given in breast milk that are made solely for the benefit of certain symbiotic bacteria (humans can’t even digest those particular nutrients, we literally evolved to produce some nutrients solely for the bacteria).

See also: Breast Milk’s Benefits That Are (So Far) Not Replicable

However, it still goes for the rest of us who are not babies, too. We could, Dr. Chutkan tells us, stand to wash less in general, and definitely ease up on antibacterial soaps and so forth.

Take antibiotics only if absolutely necessary (and avoid taking them by proxy)

Dr. Chutkan describes antibiotics as the single biggest threat to our microbiome, not just because of overprescription, but also the antibiotics that are used in animal agriculture and thus enter the food chain (and thus, enter us, if we eat animal products).

Still, while the antibiotics meat/dairy-enjoyers will get from food are better avoided, antibiotics actually taken directly are even worse, and are absolutely a “scorched earth” tactic against whatever they’re being prescribed for.

See also: Antibiotics? Think Thrice ← which also brings up “Four Ways Antibiotics Can Kill You”; seriously, the risks of antibiotics are not to be underestimated, including the risks associated only with them working exactly as intended—let alone if something goes wrong.

Probiotics won’t save you

While like any gastroenterologist (or really, almost any person in general), she notes that probiotics can give a boost to health. However, she wants us to know about two shortcomings that are little-discussed:

1) Your body has a collection of microbiomes each with their own needs, and while it is possible to take “generally good” bacteria in probiotics and assume they’ll do good, taking Lactobacillus sp. will do nothing for a shortage of Bifidobacteria sp, and even taking the correct genus can have similar shortcomings if a different species of that genus is needed, e.g. taking L. acidophilus will do nothing for a shortage of L. reuteri.

It’d be like a person with a vitamin D deficiency taking vitamin B12 supplements and wondering why they’re not getting better.

2) Probiotics are often wasted if not taken mindfully of their recipient environment. For example, most gut bacteria only live for about 20 minutes in the gut. They’re usually inactive in the supplement form, they’re activated in the presence of heat and moisture and appropriate pH etc, and then the clock is ticking for them to thrive or die.

This means that if you take a supplement offering two billion strains of good gut bacteria, and you take it on an empty stomach, then congratulations, 20 minutes later, they’re mostly dead, because they had nothing to eat. Or if you take it after drinking a soda, congratulations, they’re mostly dead because not only were they starved, but also their competing “bad” microbes weren’t starved and changed the environment to make it worse for the “good” ones.

For this reason, taking probiotics with (or immediately after) plenty of fiber is best.

This is all accentuated if you’re recovering from using antibiotics, by the way.

Imagine: a nuclear war devastates the population of the Earth. Some astronauts manage to safely return, finding a mostly-dead world covered in nuclear winter. Is the addition of a few astronauts going to quickly repopulate the world? No, of course not. They are few, the death toll is many, and the environment is very hostile to life. A hundred years later, the population will be pretty much the same—a few straggling survivors.

It’s the same after taking antibiotics, just, generations pass in minutes instead of decades. You can’t wipe out almost everything beneficial in the gut, create a hostile environment there, throw in a couple of probiotic gummies, and expect the population to bounce back.

That said, although “probiotics will not save you”, they can help provided you give them a nice soft bed of fiber to land on, some is better than none, and guessing at what strains are needed is better than giving nothing.

What she recommends

So to recap, we’ve had:

  • Wash less, and/or with less harsh chemicals
  • Avoid antibiotics like the plague, unless you literally have The Plague, for which the treatment is indeed antibiotics
  • Avoid antibiotic-contaminated foods, which in the US is pretty much all animal products unless it’s, for example, your own back-yard hens whom you did not give antibiotics. Do not fall for greenwashing aesthetics in the packaging of “happy cows” and their beef, milk, etc, “happy hens” and their meat, eggs, etc… If it doesn’t explicitly claim to be free from the use of antibiotics, then antibiotics were almost certainly used.
    • Dr. Chutkan herself is not even vegan, by the way, but very much wants us to be able to make informed choices about this, and does recommend at least a “plants-forward” diet, for the avoiding-antibiotics reason and for the plenty-of-fiber reason, amongst others.
  • Consider probiotics, but don’t expect them to work miracles by themselves; you’ve got to help them to help you.
    • Dr. Chutkan also recommends getting microbiome tests done if you think something might be amiss, and then you can supplement with probiotics in a more targetted fashion instead of guessing at what species is needed where.

She also recommends, of course, a good gut-healthy diet in general, especially “leafy green things that were recently alive; not powders”, beans, and nuts, while avoiding gut-unhealthy things such as sugars-without-fiber, alcohol, or some gut-harmful additives (such as most artificial sweeteners, although stevia is a gut-healthy exception, and sucralose is ok in moderation).

  • Older Men’s Connections Often Wither When They’re on Their Own

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    At age 66, South Carolina physician Paul Rousseau decided to retire after tending for decades to the suffering of people who were seriously ill or dying. It was a difficult and emotionally fraught transition.

    “I didn’t know what I was going to do, where I was going to go,” he told me, describing a period of crisis that began in 2017.

    Seeking a change of venue, Rousseau moved to the mountains of North Carolina, the start of an extended period of wandering. Soon, a sense of emptiness enveloped him. He had no friends or hobbies — his work as a doctor had been all-consuming. Former colleagues didn’t get in touch, nor did he reach out.

    His wife had passed away after a painful illness a decade earlier. Rousseau was estranged from one adult daughter and in only occasional contact with another. His isolation mounted as his three dogs, his most reliable companions, died.

    Rousseau was completely alone — without friends, family, or a professional identity — and overcome by a sense of loss.

    “I was a somewhat distinguished physician with a 60-page resume,” Rousseau, now 73, wrote in the Journal of the American Geriatrics Society in May. “Now, I’m ‘no one,’ a retired, forgotten old man who dithers away the days.”

    In some ways, older men living alone are disadvantaged compared with older women in similar circumstances. Research shows that men tend to have fewer friends than women and be less inclined to make new friends. Often, they’re reluctant to ask for help.

    “Men have a harder time being connected and reaching out,” said Robert Waldinger, a psychiatrist who directs the Harvard Study of Adult Development, which has traced the arc of hundreds of men’s lives over a span of more than eight decades. The men in the study who fared the worst, Waldinger said, “didn’t have friendships and things they were interested in — and couldn’t find them.” He recommends that men invest in their “social fitness” in addition to their physical fitness to ensure they have satisfying social interactions.

    Slightly more than 1 in every 5 men ages 65 to 74 live alone, according to 2022 Census Bureau data. That rises to nearly 1 in 4 for those 75 or older. Nearly 40% of these men are divorced, 31% are widowed, and 21% never married.

    That’s a significant change from 2000, when only 1 in 6 older men lived by themselves. Longer life spans for men and rising divorce rates are contributing to the trend. It’s difficult to find information about this group — which is dwarfed by the number of women who live alone — because it hasn’t been studied in depth. But psychologists and psychiatrists say these older men can be quite vulnerable.

    When men are widowed, their health and well-being tend to decline more than women’s.

    “Older men have a tendency to ruminate, to get into our heads with worries and fears and to feel more lonely and isolated,” said Jed Diamond, 80, a therapist and the author of “Surviving Male Menopause” and “The Irritable Male Syndrome.”

    Add in the decline of civic institutions where men used to congregate — think of the Elks or the Shriners — and older men’s reduced ability to participate in athletic activities, and the result is a lack of stimulation and the loss of a sense of belonging.

    Depression can ensue, fueling excessive alcohol use, accidents, or, in the most extreme cases, suicide. Of all age groups in the United States, men over age 75 have the highest suicide rate, by far.

    For this column, I spoke at length to several older men who live alone. All but two (who’d been divorced) were widowed. Their experiences don’t represent all men who live alone. But still, they’re revealing.

    The first person I called was Art Koff, 88, of Chicago, a longtime marketing executive I’d known for several years. When I reached out in January, I learned that Koff’s wife, Norma, had died the year before, leaving him hobbled by grief. Uninterested in eating and beset by unremitting loneliness, Koff lost 45 pounds.

    “I’ve had a long and wonderful life, and I have lots of family and lots of friends who are terrific,” Koff told me. But now, he said, “nothing is of interest to me any longer.”

    “I’m not happy living this life,” he said.

    Nine days later, I learned that Koff had died. His nephew, Alexander Koff, said he had passed out and was gone within a day. The death certificate cited “end stage protein calorie malnutrition” as the cause.

    The transition from being coupled to being single can be profoundly disorienting for older men. Lodovico Balducci, 80, was married to his wife, Claudia, for 52 years before she died in October 2023. Balducci, a renowned physician known as the “patriarch of geriatric oncology,” wrote about his emotional reaction in the Journal of the American Geriatrics Society, likening Claudia’s death to an “amputation.”

    “I find myself talking to her all the time, most of the time in my head,” Balducci told me in a phone conversation. When I asked him whom he confides in, he admitted, “Maybe I don’t have any close friends.”

    Disoriented and disorganized since Claudia died, he said his “anxiety has exploded.”

    We spoke in late February. Two weeks later, Balducci moved from Tampa to New Orleans, to be near his son and daughter-in-law and their two teenagers.

    “I am planning to help as much as possible with my grandchildren,” he said. “Life has to go on.”

    Verne Ostrander, a carpenter in the small town of Willits, California, about 140 miles north of San Francisco, was reflective when I spoke with him, also in late February. His second wife, Cindy Morninglight, died four years ago after a long battle with cancer.

    “Here I am, almost 80 years old — alone,” Ostrander said. “Who would have guessed?”

    When Ostrander isn’t painting watercolors, composing music, or playing guitar, “I fall into this lonely state, and I cry quite a bit,” he told me. “I don’t ignore those feelings. I let myself feel them. It’s like therapy.”

    Ostrander has lived in Willits for nearly 50 years and belongs to a men’s group and a couples’ group that’s been meeting for 20 years. He’s in remarkably good health and in close touch with his three adult children, who live within easy driving distance.

    “The hard part of living alone is missing Cindy,” he told me. “The good part is the freedom to do whatever I want. My goal is to live another 20 to 30 years and become a better artist and get to know my kids when they get older.”

    The Rev. Johnny Walker, 76, lives in a low-income apartment building in a financially challenged neighborhood on Chicago’s West Side. Twice divorced, he’s been on his own for five years. He, too, has close family connections. At least one of his several children and grandchildren checks in on him every day.

    Walker says he had a life-changing religious conversion in 1993. Since then, he has depended on his faith and his church for a sense of meaning and community.

    “It’s not hard being alone,” Walker said when I asked whether he was lonely. “I accept Christ in my life, and he said that he would never leave us or forsake us. When I wake up in the morning, that’s a new blessing. I just thank God that he has brought me this far.”

    Waldinger recommended that men “make an effort every day to be in touch with people. Find what you love — golf, gardening, birdwatching, pickleball, working on a political campaign — and pursue it,” he said. “Put yourself in a situation where you’re going to see the same people over and over again. Because that’s the most natural way conversations get struck up and friendships start to develop.”

    Rousseau, the retired South Carolina doctor, said he doesn’t think about the future much. After feeling lost for several years, he moved across the country to Jackson, Wyoming, in the summer of 2023. He embraced solitude, choosing a remarkably isolated spot to live — a 150-square-foot cabin with no running water and no bathroom, surrounded by 25,000 undeveloped acres of public and privately owned land.

    “Yes, I’m still lonely, but the nature and the beauty here totally changed me and focused me on what’s really important,” he told me, describing a feeling of redemption in his solitude.

    Rousseau realizes that the death of his parents and a very close friend in his childhood left him with a sense of loss that he kept at bay for most of his life. Now, he said, rather than denying his vulnerability, he’s trying to live with it. “There’s only so long you can put off dealing with all the things you’re trying to escape from.”

    It’s not the life he envisioned, but it’s one that fits him, Rousseau said. He stays busy with volunteer activities — cleaning tanks and running tours at Jackson’s fish hatchery, serving as a part-time park ranger, and maintaining trails in nearby national forests. Those activities put him in touch with other people, mostly strangers, only intermittently.

    What will happen to him when this way of living is no longer possible?

    “I wish I had an answer, but I don’t,” Rousseau said. “I don’t see my daughters taking care of me. As far as someone else, I don’t think there’s anyone else who’s going to help me.”

    1) Grill the eggplant slices until soft.

    2) Spread hummus generously on one side of both slices of bread.

    2) Add the black beans on top of one slice (the hummus will help them stay in place), followed by the sun-dried tomatoes and then the eggplant. Top with the other slice of bread, hummus-side down.

    3) Coat (carefully, please) the inside of the panini press (both interior sides) with olive oil. If you don’t have sprayable oil, using a sheet of kitchen roll to apply the oil is a good way to do it without making a mess.

    4) Grill the assembled sandwich, until the bread starts to brown and the insides are warm; this should take about 4 minutes.

  • Fluoride Toothpaste vs Non-Fluoride Toothpaste – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing fluoride toothpaste to non-fluoride toothpaste, we picked the fluoride.

    Why?

    Fluoride is indeed toxic; that’s why it’s in toothpaste (to kill things; namely, bacteria whose waste products would harm our teeth). However, we are much bigger than those bacteria.

    Given the amount of fluoride in toothpaste (usually under 1mg per strip of toothpaste to cover a toothbrush head), the amount that people swallow unintentionally (about 1/20th of that, so about 0.1mg daily if brushing teeth twice daily), and the toxicity level of fluoride (32–64mg/kg), then even if we take the most dangerous ends of all those numbers (and an average body size), to suffer ill effects from fluoride due to brushing your teeth, would require that you brush your teeth more than 23,000 times per day.

    Alternatively, if you were to ravenously eat the toothpaste instead of spitting it out, you’d only need to brush your teeth a little over 1,000 times per day.

    All the same, please don’t eat toothpaste; that’s not the message here.

    However! In head-to-head tests, fluoride toothpaste has almost always beaten non-fluoride toothpaste.

    Almost? Yes, almost: hydroxyapatite performed equally in one study, but that’s not usually an option on as many supermarket shelves.

    We found some on Amazon, though, which is the one we used for today’s head-to-head. Here it is:

    Boka Fluoride-Free Toothpaste

    However, before you rush to buy it, do be aware that the toxicity of hydroxyapatite appears to be about twice that of fluoride:

    Scientific Committee on Consumer Safety Opinion On Hydroxyapatite (Nano)

    …which is still very safe (you’d need to brush your teeth, and eat all the toothpaste, about 500 times per day, to get to toxic levels, if we run with the same numbers we discussed before. Again, please do not do that, though).

    But, since the science so far suggests it’s about twice as toxic as fluoride, then regardless of that still being very safe, the fluoride is obviously (by the same metric) twice as safe, hence picking the fluoride.

    Health Insider explains in super-simple fashion why and how to do Intermittent Fasting (IF), which is something that can sound complicated at first, but becomes very simple and easy once understood.

    What do we need to know?

    Intermittent fasting (IF) is a good, well-evidenced way to ease your body’s metabolic load, and
    give your organs a chance to recover from the strain of digestion and its effects. That’s not just your gastrointestinal organs! It’s your pancreas and liver too, amongst others—this is about glucose metabolism as much as it is about digestion.

    This, in turn, allows your body some downtime to do its favorite thing, which is: maintenance!

    This maintenance takes the form of enhanced cellular apoptosis and autophagy, helping to keep cells young and cancer-free.

    In other words, with well-practised intermittent fasting, we can reduce our risk of metabolic disease (including heart disease and diabetes) as well as cancer and neurodegeneration.

    You may be wondering: this sounds miraculous; what’s the catch? There are a couple:

    • While fasting from food, the body’s enhanced metabolism requires more water, so you’ll need to take extra care keep on top of your hydration (this is one reason why Ramadan fasting, while healthy for most people, is not as healthy as IF—because Ramadan fasting means abstaining from water, too).
    • If you are diabetic, and especially if you have Type 1 Diabetes, fasting may not be a safe option for you, since if you get a hypo in the middle of your fasting period, it’s obviously not a good idea to wait another many hours before fixing it.

    Extra note on that last one: it’s easy to think “can’t I just lower my bolus insulin instead of eating?” and while superficially yes that will raise your blood sugar levels, it’s because the sugar will be sticking around in your blood, and not actually getting released into the organs that need it. So while your blood glucose monitor may say you’re fine, you will be starving your organs and if you keep it up they may suffer serious damage.

    Disclaimer: our standard legal/medical disclaimer applies, and this is intended for educational purposes only; please do speak with your endocrinologist before changing anything you usually do with regard to your blood sugar maintenance.

    Ok, back onto the cheerier topic at hand:

    Aside from the above: for most people, IF is a remarkably healthful practice in very many ways.

  • Stay away from collarium sunbeds to avoid the big risk of collapsing with a bad tan.

    What are ‘collarium’ sunbeds? Here’s why you should stay away

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Reports have recently emerged that solariums, or sunbeds – largely banned in Australia because they increase the risk of skin cancer – are being rebranded as “collarium” sunbeds (“coll” being short for collagen).

    Commercial tanning and beauty salons in Queensland, New South Wales and Victoria are marketing collariums, with manufacturers and operators claiming they provide a longer lasting tan and stimulate collagen production, among other purported benefits.

    A collarium sunbed emits both UV radiation and a mix of visible wavelength colours to produce a pink or red light. Like an old-school sunbed, the user lies in it for ten to 20 minute sessions to quickly develop a tan.

    But as several experts have argued, the providers’ claims about safety and effectiveness don’t stack up.

    Why were sunbeds banned?

    Commercial sunbeds have been illegal across Australia since 2016 (except for in the Northern Territory) under state-based radiation safety laws. It’s still legal to sell and own a sunbed for private use.

    Their dangers were highlighted by young Australians including Clare Oliver who developed melanoma after using sunbeds. Oliver featured in the No Tan Is Worth Dying For campaign and died from her melanoma at age 26 in 2007.

    Sunbeds lead to tanning by emitting UV radiation – as much as six times the amount of UV we’re exposed to from the summer sun. When the skin detects enough DNA damage, it boosts the production of melanin, the brown pigment that gives you the tanned look, to try to filter some UV out before it hits the DNA. This is only partially successful, providing the equivalent of two to four SPF.

    Essentially, if your body is producing a tan, it has detected a significant amount of DNA damage in your skin.

    Research shows people who have used sunbeds at least once have a 41% increased risk of developing melanoma, while ten or more sunbed sessions led to a 100% increased risk.

    In 2008, Australian researchers estimated that each year, sunbeds caused 281 cases of melanoma, 2,572 cases of squamous cell carcinoma (another common type of skin cancer), and $3 million in heath-care costs, mostly to Medicare.

    How are collarium sunbeds supposed to be different?

    Australian sellers of collarium sunbeds imply they are safe, but their machine descriptions note the use of UV radiation, particularly UVA.

    UVA is one part of the spectrum of UV radiation. It penetrates deeper into the skin than UVB. While UVB promotes cancer-causing mutations by discharging energy straight into the DNA strand, UVA sets off damage by creating reactive oxygen species, which are unstable compounds that react easily with many types of cell structures and molecules. These damage cell membranes, protein structures and DNA.

    Evidence shows all types of sunbeds increase the risk of melanoma, including those that use only UVA.

    Some manufacturers and clinics suggest the machine’s light spectrum increases UV compatibility, but it’s not clear what this means. Adding red or pink light to the mix won’t negate the harm from the UV. If you’re getting a tan, you have a significant amount of DNA damage.

    Collagen claims

    One particularly odd claim about collarium sunbeds is that they stimulate collagen.

    Collagen is the main supportive tissue in our skin. It provides elasticity and strength, and a youthful appearance. Collagen is constantly synthesised and broken down, and when the balance between production and recycling is lost, the skin loses strength and develops wrinkles. The collagen bundles become thin and fragmented. This is a natural part of ageing, but is accelerated by UV exposure.

    Sun-damaged skin and sun-protected skin from the same person, and the microscopic image of each showing how the collagen bundles have been thinned out in the sun-damaged skin.
    Sun-protected skin (top) has thick bands of pink collagen (arrows) in the dermis, as seen on microscopic examination. Chronically sun-damaged skin (bottom) has much thinner collagen bands.
    Katie Lee/UQ

    The reactive oxygen species generated by UVA light damage existing collagen structures and kick off a molecular chain of events that downgrades collagen-producing enzymes and increases collagen-destroying enzymes. Over time, a build-up of degraded collagen fragments in the skin promotes even more destruction.

    While there is growing evidence red light therapy alone could be useful in wound healing and skin rejuvenation, the UV radiation in collarium sunbeds is likely to undo any benefit from the red light.

    What about phototherapy?

    There are medical treatments that use controlled UV radiation doses to treat chronic inflammatory skin diseases like psoriasis.

    The anti-collagen effects of UVA can also be used to treat thickened scars and keloids. Side-effects of UV phototherapy include tanning, itchiness, dryness, cold sore virus reactivation and, notably, premature skin ageing.

    These treatments use the minimum exposure necessary to treat the condition, and are usually restricted to the affected body part to minimise risks of future cancer. They are administered under medical supervision and are not recommended for people already at high risk of skin cancer, such as people with atypical moles.

    So what happens now?

    It looks like many collariums are just sunbeds rebranded with red light. Queensland Health is currently investigating whether these salons are breaching the state’s Radiation Safety Act, and operators could face large fines.

    As the 2024 Australians of the Year – melanoma treatment pioneers Georgina Long and Richard Scolyer – highlighted in their acceptance speech, “there is nothing healthy about a tan”, and we need to stop glamorising tanning.

    However, if you’re desperate for the tanned look, there is a safer and easy way to get one – out of a bottle or by visiting a salon for a spray tan.The Conversation

  • When Age Is A Flexible Number

    Aging, Counterclockwise!

    In the late 1970s, Dr. Ellen Langer hypothesized that physical markers of aging could be affected by psychosomatic means.

    Note: psychosomatic does not mean “it’s all in your head”.

    Psychosomatic means “your body does what your brain tells it to do, for better or for worse”

    She set about testing that, in what has been referred to since as…

    The Counterclockwise Study

    A small (n=16) sample of men in their late 70s and early 80s were recruited in what they were told was a study about reminiscing.

    Back in the 1970s, it was still standard practice in the field of psychology to outright lie to participants (who in those days were called “subjects”), so this slight obfuscation was a much smaller ethical aberration than in some famous studies of the same era and earlier (cough cough Zimbardo cough Milgram cough).

    Anyway, the participants were treated to a week in a 1950s-themed retreat, specifically 1959, a date twenty years prior to the experiment’s date in 1979. The environment was decorated and furnished authentically to the date, down to the food and the available magazines and TV/radio shows; period-typical clothing was also provided, and so forth.

    • The control group were told to spend the time reminiscing about 1959
    • The experimental group were told to pretend (and maintain the pretense, for the duration) that it really was 1959

    The results? On many measures of aging, the experimental group participants became quantifiably younger:

    ❝The experimental group showed greater improvement in joint flexibility, finger length (their arthritis diminished and they were able to straighten their fingers more), and manual dexterity.

    On intelligence tests, 63 percent of the experimental group improved their scores, compared with only 44 percent of the control group. There were also improvements in height, weight, gait, and posture.

    Finally, we asked people unaware of the study’s purpose to compare photos taken of the participants at the end of the week with those submitted at the beginning of the study. These objective observers judged that all of the experimental participants looked noticeably younger at the end of the study.❞

    Remember, this was after one week.

    Her famous study was completed in 1979, and/but not published until eleven years later in 1990, with the innocuous title:

    Higher stages of human development: Perspectives on adult growth

    You can read about it much more accessibly, and in much more detail, in her book:

    Counterclockwise: A Proven Way to Think Yourself Younger and Healthier – by Dr. Ellen Langer

    We haven’t reviewed that particular book yet, so here’s Linda Graham’s review, that noted:

    ❝Langer cites other research that has made similar findings.

    In one study, for instance, 650 people were surveyed about their attitudes on aging. Twenty years later, those with a positive attitude with regard to aging had lived seven years longer on average than those with a negative attitude to aging.

    (By comparison, researchers estimate that we extend our lives by four years if we lower our blood pressure and reduce our cholesterol.)

    In another study, participants read a list of negative words about aging; within 15 minutes, they were walking more slowly than they had before.❞

    ~ Linda Graham

    Aging in Reverse: A Review of Counterclockwise

    The Counterclockwise study has been repeated since, and/but we are still waiting for the latest (exciting, much larger sample, 90 participants this time) study to be published. The research proposal describes the method in great detail, and you can read that with one click over on PubMed:

    PubMed | Ageing as a mindset: a study protocol to rejuvenate older adults with a counterclockwise psychological intervention

    It was approved, and has now been completed (as of 2020), but the results have not been published yet; you can see the timeline of how that’s progressing over on ClinicalTrials.gov:

    Clinical Trials | Ageing as a Mindset: A Counterclockwise Experiment to Rejuvenate Older Adults

    Hopefully it’ll take less time than the eleven years it took for the original study, but in the meantime, there seems to be nothing to lose in doing a little “Citizen Science” for ourselves.

    Maybe a week in a 20 years-ago themed resort (writer’s note: wow, that would only be 2004; that doesn’t feel right; it should surely be at least the 90s!) isn’t a viable option for you, but we’re willing to bet it’s possible to “microdose” on this method. Given that the original study lasted only a week, even just a themed date-night on a regular recurring basis seems like a great option to explore (if you’re not partnered then well, indulge yourself how best you see fit, in accord with the same premise; a date-night can be with yourself too!).

    Just remember the most important take-away though:

    Don’t accidentally put yourself in your own control group!

    In other words, it’s critically important that for the duration of the exercise, you act and even think as though it is the appropriate date.

    If you instead spend your time thinking “wow, I miss the [decade that does it for you]”, you will dodge the benefits, and potentially even make yourself feel (and thus, potentially, if the inverse hypothesis holds true, become) older.

    This latter is not just our hypothesis by the way, there is an established potential for nocebo effect.

    For example, the following study looked at how instructions given in clinical tests can be worded in a way that make people feel differently about their age, and impact the results of the mental and/or physical tests then administered:

    ❝Our results seem to suggest how manipulations by instructions appeared to be more largely used and capable of producing more clear performance variations on cognitive, memory, and physical tasks.

    Age-related stereotypes showed potentially stronger effects when they are negative, implicit, and temporally closer to the test of performance. ❞
