Vaccines and cancer: The myth that won’t die

Two recent studies reported rising cancer rates among younger adults in the U.S. and worldwide. This prompted some online anti-vaccine accounts to link the studies’ findings to COVID-19 vaccines. 

But, as with other myths, the data tells a very different story. 

What you need to know 

  • Baseless claims that COVID-19 vaccines cause cancer have persisted online for several years and gained traction in late 2023.
  • Two recent reports finding rising cancer rates among younger adults are based on pre-pandemic cancer incidence data. Cancer rates in the U.S. have been on the rise since the 1990s.
  • There is no evidence of a link between COVID-19 vaccination and increased cancer risk.

False claims about COVID-19 vaccines began circulating months before the vaccines were available. Chief among these claims was misinformed speculation that vaccine mRNA could alter or integrate into vaccine recipients’ DNA. 

It does not. But that didn’t prevent some on social media from spinning that claim into a persistent myth alleging that mRNA vaccines can cause or accelerate cancer growth. Anti-vaccine groups even coined the term “turbo cancer” to describe a fake phenomenon of abnormally aggressive cancers allegedly linked to COVID-19 vaccines. 

They used the American Cancer Society’s 2024 cancer projection—based on incidence data through 2020—and a study of global cancer trends between 1999 and 2019 to bolster the false claims. This exposed the dishonesty at the heart of the anti-vaccine messaging, as data that predated the pandemic by decades was carelessly linked to COVID-19 vaccines in viral social media posts.

Some on social media cherry-pick data and use unfounded evidence because the claims that COVID-19 vaccines cause cancer are not true. According to the National Cancer Institute and American Cancer Society, there is no evidence of any link between COVID-19 vaccines and an increase in cancer diagnosis, progression, or remission. 

Why does the vaccine cancer myth endure?

At the root of false cancer claims about COVID-19 vaccines is a long history of anti-vaccine figures falsely linking vaccines to cancer. Polio and HPV vaccines have both been the target of disproven cancer myths. 

Not only do HPV vaccines not cause cancer, they are one of only two vaccines that prevent cancer.

In the case of polio vaccines, some early batches were contaminated with simian virus 40 (SV40), a virus that is known to cause cancer in some mammals but not humans. The contaminated batches were discovered, and no other vaccine has had SV40 contamination in over 60 years

Follow-up studies found no increase in cancer rates in people who received the SV40-contaminated polio vaccine. Yet, vaccine opponents have for decades claimed that polio vaccines cause cancer.

Recycling of the SV40 myth

The SV40 myth resurfaced in 2023 when vaccine opponents claimed that COVID-19 vaccines contain the virus. In reality, a small, nonfunctional piece of the SV40 virus is used in the production of some COVID-19 vaccines. This DNA fragment, called the promoter, is commonly used in biomedical research and vaccine development and doesn’t remain in the finished product. 

Crucially, the SV40 promoter used to produce COVID-19 vaccines doesn’t contain the part of the virus that enters the cell nucleus and is associated with cancer-causing properties in some animals. The promoter also lacks the ability to survive on its own inside the cell or interact with DNA. In other words, it poses no risk to humans.

Over 5.6 billion people worldwide have received COVID-19 vaccines since December 2020. At that scale, even the tiniest increase in cancer rates in vaccinated populations would equal hundreds of thousands of excess cancer diagnoses and deaths. The evidence for alleged vaccine-linked cancer would be observed in real incidence, treatment, and mortality data, not social media anecdotes or unverifiable reports.

  • The Mental Health First-Aid That You’ll Hopefully Never Need

    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.

    Take Your Mental Health As Seriously As General Health!

    Sometimes, health and productivity means excelling—sometimes, it means avoiding illness and unproductivity. Both are essential, and today we’re going to tackle some ground-up stuff. If you don’t need it right now, great; we suggest to read it for when and if you do. But how likely is it that you will?

    • One in four of us are affected by serious mental health issues in any given year.
    • One in five of us have suicidal thoughts at some point in our lifetime.
    • One in six of us are affected to at least some extent by the most commonly-reported mental health issues, anxiety and depression, in any given week.

    …and that’s just what’s reported, of course. These stats are from a UK-based source but can be considered indicative generally. Jokes aside, the UK is not a special case and is not measurably worse for people’s mental health than, say, the US or Canada.

    While this is not an inherently cheery topic, we think it’s an important one.

    Depression, which we’re going to focus on today, is very very much a killer to both health and productivity, after all.

    One of the most commonly-used measures of depression is known by the snappy name of “PHQ9”. It stands for “Patient Health Questionnaire Nine”, and you can take it anonymously online for free (without signing up for anything; it’s right there on the page already):

    Take The PHQ9 Test Here! (under 2 minutes, immediate results)

    There’s a chance you took that test and your score was, well, depressing. There’s also a chance you’re doing just peachy, or maybe somewhere in between. PHQ9 scores can fluctuate over time (because they focus on the past two weeks, and also rely on self-reports in the moment), so you might want to bookmark it to test again periodically. It can be interesting to track over time.

    In the event that you’re struggling (or: in case one day you find yourself struggling, or want to be able to support a loved one who is struggling), some top tips that are useful:

    Accept that it’s a medical condition like any other

    Which means some important things:

    • You/they are not lazy or otherwise being a bad person by being depressed
    • You/they will probably get better at some point, especially if help is available
    • You/they cannot, however, “just snap out of it”; illness doesn’t work that way
    • Medication might help (it also might not)

    Do what you can, how you can, when you can

    Everyone knows the advice to exercise as a remedy for depression, and indeed, exercise helps many. Unfortunately, it’s not always that easy.

    Did you ever see the 80s kids’ movie “The Neverending Story”? There’s a scene in which the young hero Atreyu must traverse the “Swamp of Sadness”, and while he has a magical talisman that protects him, his beloved horse Artax is not so lucky; he slows down, and eventually stops still, sinking slowly into the swamp. Atreyu pulls at him and begs him to keep going, but—despite being many times bigger and stronger than Atreyu, the horse just sinks into the swamp, literally drowning in despair.

    See the scene: The Neverending Story movie clip – Artax and the Swamp of Sadness (1984)

    Wow, they really don’t make kids’ movies like they used to, do they?

    But, depression is very much like that, and advice “exercise to feel less depressed!” falls short of actually being helpful, when one is too depressed to do it.

    If you’re in the position of supporting someone who’s depressed, the best tool in your toolbox will be not “here’s why you should do this” (they don’t care; not because they’re an uncaring person by nature, but because they are physiologically impeded from caring about themself at this time), but rather:

    “please do this with me”

    The reason this has a better chance of working is because the depressed person will in all likelihood be unable to care enough to raise and/or maintain an objection, and while they can’t remember why they should care about themself, they’re more likely to remember that they should care about you, and so will go with your want/need more easily than with their own. It’s not a magic bullet, but it’s worth a shot.

    What if I’m the depressed person, though?

    Honestly, the same, if there’s someone around you that you do care about; do what you can to look after you, for them, if that means you can find some extra motivation.

    But I’m all alone… what now?

    Firstly, you don’t have to be alone. There are free services that you can access, for example:

    …which varyingly offer advice, free phone services, webchats, and the like.

    But also, there are ways you can look after yourself a little bit; do the things you’d advise someone else to do, even if you’re sure they won’t work:

    • Take a little walk around the block
    • Put the lights on when you’re not sleeping
    • For that matter, get out of bed when you’re not sleeping. Literally lie on the floor if necessary, but change your location.
    • Change your bedding, or at least your clothes
    • If changing the bedding is too much, change just the pillowcase
    • If changing your clothes is too much, change just one item of clothing
    • Drink some water; it won’t magically cure you, but you’ll be in slightly better order
    • On the topic of water, splash some on your face, if showering/bathing is too much right now
    • Do something creative (that’s not self-harm). You may scoff at the notion of “art therapy” helping, but this is a way to get at least some of the lights on in areas of your brain that are a little dark right now. Worst case scenario is it’ll be a distraction from your problems, so give it a try.
    • Find a connection to community—whatever that means to you—even if you don’t feel you can join it right now. Discover that there are people out there who would welcome you if you were able to go join them. Maybe one day you will!
    • Hiding from the world? That’s probably not healthy, but while you’re hiding, take the time to read those books (write those books, if you’re so inclined), learn that new language, take up chess, take up baking, whatever. If you can find something that means anything to you, go with that for now, ride that wave. Motivation’s hard to come by during depression and you might let many things slide; you might as well get something out of this period if you can.

    If you’re not depressed right now but you know you’re predisposed to such / can slip that way?

    Write yourself instructions now. Copy the above list if you like.

    Most of all: have a “things to do when I don’t feel like doing anything” list.

    If you only take one piece of advice from today’s newsletter, let that one be it!

  • The S.T.E.P.S. To A Healthier Heart

    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.

    Stepping Into Better Heart Health

    This is Dr. Jennifer H. Mieres, FACC, FAHA, MASNC. she’s an award-winning (we counted 9 major awards) professor of cardiology, and a leading advocate for women’s heart health. This latter she’s done via >70 scientific publications, >100 research presentations at national and international conferences, 3 books so far, and 4 documentaries, including the Emmy-nominated “A Woman’s Heart”.

    What does she want us to know?

    A lot of her work is a top-down approach, working to revolutionize the field of cardiology in its application, to result in far fewer deaths annually. Which is fascinating, but unless you’re well-placed in that industry, not something too actionable as an individual (if you are well-placed in that industry, do look her up, of course).

    For the rest of us…

    Dr. Mieres’ S.T.E.P.S. to good heart health

    She wants us to do the following things:

    1) Stock your kitchen with heart health in mind

    This is tied to the third item in the list of course, but it’s a critical step not to be overlooked. It’s all very well to know “eat more fiber; eat less red meat” and so forth, but if you go to your kitchen and what’s there is not conducive to heart health, you’re just going to do the best with what’s available.

    Instead, actually buy foods that are high in fiber, and preferably, foods that you like. Not a fan of beans? Don’t buy them. Love pasta? Go wholegrain. Like leafy greens in principle, but they don’t go with what you cook? Look up some recipes, and then buy them.

    Love a beef steak? Well we won’t lie to you, that is not good for your heart, but make it a rare option—so to speak—and enjoy it mindfully (see also: mindful eating) once in a blue moon for a special occasion, rather than “I don’t know what to cook tonight, so sizzle sizzle I guess”.

    Meal planning goes a long way for this one! And if meal-planning sounds like an overwhelming project to take on, then consider trying one of the many healthy-eating meal kit services that will deliver ingredients (and their recipes) to your door—opting for a plants-forward plan, and the rest should fall into place.

    2) Take control of your activity

    Choose to move! Rather than focusing on what you can’t do (let’s say, those 5am runs, or your regularly-scheduled, irregularly attended, gym sessions), focus on what you can do, and do it.

    See also: No-Exercise Exercise!

    3) Eat for a healthier heart

    This means following through on what you did on the first step, and keeping it that way. Buying fresh fruit and veg is great, but you also have to actually eat it. Do not let the perishables perish!

    For you too, dear reader, are perishable (and would presumably like to avoid perishing).

    This item in the list may seem flippant, but actually this is about habit-forming, and without it, the whole plan will grind to a halt a few days after your first heart-health-focused shopping trip.

    See also: Where Nutrition Meets Habits!

    4) Partner with your doctor, family, and friends

    Good relationships, both professional and personal, count for a lot. Draw up a plan with your doctor; don’t just guess at when to get this or that checked—or what to do about it if the numbers aren’t to your liking.

    Partnership with your doctor goes both ways, incidentally. Read up, have opinions, discuss them! Doing so will ultimately result in better care than just going in blind and coming out with a recommendation you don’t understand and just trust (but soon forget, because you didn’t understand).

    And as for family and friends, this is partly about social factors—we tend to influence, and be influenced by, those around us. It can be tricky to be on a health kick if your partner wants take-out every night, so some manner of getting everyone on the same page is important, be it by compromise or, in an ideal world, gradually trending towards better health. But any such changes must come from a place of genuine understanding and volition, otherwise at best they won’t stick, and at worst they’ll actively create a pushback.

    Same goes for exercise as for diet—exercising together is a good way to boost commitment, especially if it’s something fun (dance classes are a fine example that many couples enjoy, for example).

    5) Sleep more, stress less, savor life

    These things matter a lot! Many people focus on cutting down salt or saturated fat, and that can be good if otherwise consumed to excess, but for most people they’re not the most decisive factors:

    Hypertension: Factors Far More Relevant Than Salt ← sleep features here!

    Stress is also a huge one, and let’s put it this way: people more often have heart attacks during a moment of excessive emotional stress—not during a moment when they had a bit too much butter on their toast.

    It’s not even just that acute stress is the trigger, it’s that chronic stress is a contributory factor that erodes the body’s ability to handle the acute stress.

    Changing this may seem “easier said than done” because often the stressors are external (e.g. work pressure, financial worries, caring for a sick relative, relationship troubles, major life change, etc), but it is possible to find peace even in the chaos of life:

  • Alzheimer’s Causative Factors To Avoid

    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.

    The Best Brains Bar Nun?

    This is Dr. David Snowdon. He’s an epidemiologist, and one of the world’s foremost experts on Alzheimer’s disease. He was also, most famously, the lead researcher of what has become known as “The Nun Study”.

    We recently reviewed his book about this study:

    Aging with Grace: What the Nun Study Teaches Us About Leading Longer, Healthier, and More Meaningful Lives – by Dr. David Snowdon

    …which we definitely encourage you to check out, but we’ll do our best to summarize its key points today!

    Reassurance up-front: no, you don’t have to become a nun

    The Nun Study

    In 1991, a large number (678) of nuns were recruited for what was to be (and until now, remains) the largest study of its kind into the impact of a wide variety of factors on aging, and in particular, Alzheimer’s disease.

    Why it was so important: because the nuns were all from the same Order, had the same occupation (it’s a teaching Order), with very similar lifestyles, schedules, socioeconomic status, general background, access to healthcare, similar diets, same relationship status (celibate), same sex (female), and many other factors also similar, this meant that most of the confounding variables that confound other studies were already controlled-for here.

    Enrollment in the study also required consenting to donating one’s brain for study post-mortem—and of those who have since died, indeed 98% of them have been donated (the other 2%, we presume, may have run into technical administrative issues with the donation process, due to the circumstances of death and/or delays in processing the donation).

    How the study was undertaken

    We don’t have enough space to describe the entire methodology here, but the gist of it is:

    • Genetic testing for relevant genetic factors
    • Data gathered about lives so far, including not just medical records but also autobiographies that the nuns wrote when they took their vows (at ages 19–21)
    • Extensive ongoing personal interviews about habits, life choices, and attitudes
    • Yearly evaluations including memory tests and physical function tests
    • Brain donation upon death

    What they found

    Technically, The Nun Study is still ongoing. Of the original 678 nuns (aged 75–106), three are still alive (based on the latest report, at least).

    However, lots of results have already been gained, including…

    Genes

    A year into the study, in 1992, the “apolipoprotein E” (APOE) gene was established as a likely causative factor in Alzheimer’s disease. This is probably not new to our readers in 2024, but there are interesting things being learned even now, for example:

    The Alzheimer’s Gene That Varies By Race & Sex

    …but watch out! Because also:

    Alzheimer’s Sex Differences May Not Be What They Appear

    Words

    Based on the autobiographies written by the nuns in their youth upon taking their vows, there were two factors that were later correlated with not getting dementia:

    • Longer sentences
    • Positive outlook
    • “Idea density”

    That latter item means the relative linguistic density of ideas and complexity thereof, and the fluency and vivacity with which they were expressed (this was not a wishy-washy assessment; there was a hard-science analysis to determine numbers).

    Want to spruce up yours? You might like to check out:

    Reading, Better: Reading As A Cognitive Exercise

    …for specific, evidence-based ways to tweak your reading to fight cognitive decline.

    Food

    While the dietary habits of the nuns were fairly homogenous, those who favored eating more and cooked greens, beans, and tomatoes, lived longer and with healthier brains.

    See also: Brain Food? The Eyes Have It!

    Other aspects of brain health & mental health

    The study also found that nuns who avoided stroke and depression, were also less likely to get dementia.

    For tending to these, check out:

    Community & Faith

    Obviously, in this matter the nuns were quite a homogenous group, scoring heavily in community and faith. What’s relevant here is the difference between the nuns, and other epidemiological studies in other groups (invariably not scoring so highly).

    Community & faith are considered, separately and together, to be protective factors against dementia.

    Faith may be something that “you have it or you don’t” (we’re a health science newsletter, not a theological publication, but for the interested, philosopher John Stuart Mill’s 1859 essay “On Liberty“ makes a good argument for it not being something one can choose, prompting him to argue for religious tolerance, on the grounds that religious coercion is a futile effort precisely because a person cannot choose to dis/believe something)

    …but community can definitely be chosen, nurtured, and grown. We’ve written about this a bit before:

    A new study has highlighted the importance of lifestyle factors in shaping the oral microbiome—that is to say, how the things we do affect the bacteria that live in our mouths:

    Nepali oral microbiomes reflect a gradient of lifestyles from traditional to industrialized

    Neither the study title nor the abstract elucidate how, exactly, one impacts the other, but the study itself does (of course) contain that information; we read it, and the short version is:

    In terms of the extremes of “most traditional” to “most industrialized”, foragers have the most diverse oral microbiomes (that’s good), and people with an American industrialized lifestyle had the least diverse oral microbiomes (that’s bad). Between the two extremes, we see the gradient promised by the title.

    If you do feel like checking it out, Figure 3 in the paper illustrates this nicely.

    Also illustrated in the above-linked Figure 3 is oral microbiome composition. In other words (and to oversimplify it rather), how good or bad our mouth bacteria are for us, independent of diversity (so for example, are there more of this or that kind of bacteria).

    Once again, there is a gradient, only this time, the ends of it are even more polarized: foragers have a diverse oral microbiome rich with healthy-for-humans bacteria, while people with an American industrialized lifestyle might not have the diversity, but do have a large number of bad-for-humans bacteria.

    While many lifestyle factors are dietary or quasi-dietary, e.g. what kinds of foods people eat, whether they drink alcohol, whether they smoke or use gum, etc, many lifestyle factors were examined, including everything from medications and exercise, to things like kitchen location and what fuel is predominantly used, to education and sexual activity and many other things that we don’t have room for here.

    You can see how each lifestyle factor stacked up, in Figure 5.

    Why it matters

    Our oral microbiome affects many aspects of health, including:

    • Locally: caries, periodontal diseases, mucosal diseases, oral cancer, and more
    • Systemically: gastrointestinal diseases in general, IBS in particular, nervous system diseases, Alzheimer’s disease, endocrine diseases, all manner of immune/autoimmune diseases, and more

    Nor are the effects it has mild; oral microbiome health can be a huge factor, statistically, for many of the above. You can see information and data pertaining to all of the above and more, here:

    Oral microbiomes: more and more importance in oral cavity and whole body

    What to do about it

    Take care of your oral microbiome, to help it to take care of you. As well as the above-mentioned lifestyle factors, it’s worth noting that when it comes to oral hygiene, not all oral hygiene products are created equal:

    Toothpastes & Mouthwashes: Which Kinds Help, And Which Kinds Harm?

    Additionally, you might want to consider gentler options, but if you do, take care to opt for things that science actually backs., rather than things that merely trended on social media.

    This writer (hi, it’s me) is particularly excited about the science and use of the miswak stick, which comes from the Saladora persica tree, and has phytochemical properties that (amongst many other health-giving effects) improve the quality of saliva (i.e., improve its pH and microbiome composition). In essence, your own saliva gets biochemically nudged into being the safest, most effective mouthwash.

    There’s a lot of science for the use of S. persica, and we’ve discussed it before in more detail than we have room to rehash today, here:

    Less Common Oral Hygiene Options

    If you’d like to enjoy these benefits (and also have the equivalent of a toothbrush that you can carry with you at all times and does not require water*), then here’s an example product on Amazon 😎

    *don’t worry, it won’t feel like dry-brushing your teeth. Remember what we said about what it does to your saliva. Basically, you chomp it once, and your saliva a) increases and b) becomes biological tooth-cleaning fluid. The stick itself is fibrous, so the end of it frays in a way that makes a natural little brush. Each stick is about 5”×¼” and you can carry it in a little carrying case (you’ll get a couple with each pack of miswak sticks), so you can easily use it in, say, the restroom of a restaurant or before your appointment somewhere, just as easily as you could use a toothpick, but with much better results. You may be wondering how long a stick lasts; well, that depends on how much you use it, but in this writer’s experience, each stick lasts about a month maybe, using it at least 2–3 times per day, probably rather more since I use it after each meal/snack and upon awakening.

    (the above may read like an ad, but we promise you it’s not sponsored and this writer’s just enthusiastic, and when you read the science, you will be too)

  • Is Chiropractic All It’s Cracked Up To Be?

    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.

    Is Chiropractic All It’s Cracked Up To Be?

    Yesterday, we asked you for your opinions on chiropractic medicine, and got the above-depicted, below-described set of results:

    • 38% of respondents said it keeps us healthy, and everyone should do it as maintenance
    • 33% of respondents said it can correct some short-term skeletal issues, but that’s all
    • 16% of respondents said that it’s a dangerous pseudoscience and can cause serious harm
    • 13% of respondents said that it’s mostly just a combination of placebo and endorphins

    Respondents also shared personal horror stories of harm done, personal success stories of things cured, and personal “it didn’t seem to do anything for me” stories.

    What does the science say?

    It’s a dangerous pseudoscience and can cause harm: True or False?

    False and True, respectively.

    That is to say, chiropractic in its simplest form that makes the fewest claims, is not a pseudoscience. If somebody physically moves your bones around, your bones will be physically moved. If your bones were indeed misaligned, and the chiropractor is knowledgeable and competent, this will be for the better.

    However, like any form of medicine, it can also cause harm; in chiropractic’s case, because it more often than not involves manipulation of the spine, this can be very serious:

    ❝Twenty six fatalities were published in the medical literature and many more might have remained unpublished.

    The reported pathology usually was a vascular accident involving the dissection of a vertebral artery.

    Conclusion: Numerous deaths have occurred after chiropractic manipulations. The risks of this treatment by far outweigh its benefit.❞

    Source: Deaths after chiropractic: a review of published cases

    From this, we might note two things:

    1. The abstract doesn’t note the initial sample size; we would rather have seen this information expressed as a percentage. Unfortunately, the full paper is not accessible, and nor are many of the papers it cites.
    2. Having a vertebral artery fatally dissected is nevertheless not an inviting prospect, and is certainly a very reasonable cause for concern.

    It’s mostly just a combination of placebo and endorphins: True or False?

    True or False, depending on what you went in for:

    • If you went in for a regular maintenance clunk-and-click, then yes, you will get your clunk-and-click and feel better for it because you had a ritualized* experience and endorphins were released.
    • If you went in for something that was actually wrong with your skeletal alignment, to get it corrected, and this correction was within your chiropractor’s competence, then yes, you will feel better because a genuine fault was corrected.

    *this is not implying any mysticism, by the way. Rather it means simply that placebo effect is strongest when there is a ritual associated with it. In this case it means going to the place, sitting in a pleasant waiting room, being called in, removing your shoes and perhaps some other clothes, getting the full attention of a confident and assured person for a while, this sort of thing.

    With regard to its use to combat specifically spinal pain (i.e., perhaps the most obvious thing to treat by chiropractic spinal manipulation), evidence is slightly in favor, but remains unclear:

    ❝Due to the low quality of evidence, the efficacy of chiropractic spinal manipulation compared with a placebo or no treatment remains uncertain. ❞

    Source: Clinical Effectiveness and Efficacy of Chiropractic Spinal Manipulation for Spine Pain

    It can correct some short-term skeletal issues, but that’s all: True or False?

    Probably True.

    Why “probably”? The effectiveness of chiropractic treatment for things other than short-term skeletal issues has barely been studied. From this, we may wish to keep an open mind, while also noting that it can hardly claim to be evidence-based—and it’s had hundreds of years to accumulate evidence. In all likelihood, publication bias has meant that studies that were conducted and found inconclusive or negative results were simply not published—but that’s just a hypothesis on our part.

    In the case of using chiropractic to treat migraines, a very-related-but-not-skeletal issue, researchers found:

    ❝Pre-specified feasibility criteria were not met, but deficits were remediable. Preliminary data support a definitive trial of MCC+ for migraine.❞

    Translating this: “it didn’t score as well as we hoped, but we can do better. We got some positive results, and would like to do another, bigger, better trial; please fund it”

    Meanwhile, chiropractors’ claims for very unrelated things have been harshly criticized by the scientific community, for example:

    Misinformation, chiropractic, and the COVID-19 pandemic

    About that “short-term” aspect, one of our subscribers put it quite succinctly:

    ❝Often a skeletal correction is required for initial alignment but the surrounding fascia and muscles also need to be treated to mobilize the joint and release deep tissue damage surrounding the area. In combination with other therapies chiropractic support is beneficial.❞

    This is, by the way, very consistent with what was said in the very clinically-dense book we reviewed yesterday, which has a chapter on the short-term benefits and limitations of chiropractic.

    A truism that holds for many musculoskeletal healthcare matters, holds true here too:

    ❝In a battle between muscle and bone, muscle will always win❞

    In other words…

    Chiropractic can definitely help put misaligned bones back where they should be. However, once they’re there, if the cause of their misalignment is not treated, they will just re-misalign themselves shortly after you walking out of your session.

    This is great for chiropractors, if it keeps you coming back for endless appointments, but it does little for your body beyond give you a brief respite.

    So, by all means go to a chiropractor if you feel so inclined (and you do not fear accidental arterial dissection etc), but please also consider going to a physiotherapist, and potentially other medical professions depending on what seems to be wrong, to see about addressing the underlying cause.

    Take care!

  • Think Again – by Adam Grant

    Warning: this book may cause some feelings of self-doubt! Ride them out and see where they go, though.

    It was Socrates who famously (allegedly) said “ἓν οἶδα ὅτι οὐδὲν οἶδα”—”I know that I know nothing”.

    Adam Grant wants us to take this philosophy and apply it usefully to modern life. How?

    The main premise is that rethinking our plans, answers and decisions is a good thing… Not a weakness. In contrast, he says, a fixed mindset closes us to opportunities—and better alternatives.

    He wants us to be sure that we don’t fall into the trap of the Dunning-Kruger Effect (overestimating our abilities because of being unaware of how little we know), but he also wants us to rethink whole strategies, too. For example:

    Grant’s approach to interpersonal conflict is very remniscent of another book we might review sometime, “Aikido in Everyday Life“. The idea here is to not give in to our knee-jerk responses to simply retaliate in kind, but rather to sidestep, pivot, redirect. This is, admittedly, the kind of “rethinking” that one usually has to rethink in advance—it’s too late in the moment! Hence the value of a book.

    Nor is the book unduly subjective. “Wishy-washiness” has a bad rep, but Grant gives us plenty in the way of data and examples of how we can, for example, avoid losses by not doubling down on a mistake.

    What, then, of strongly-held core principles? Rethinking doesn’t mean we must change our mind—it simply means being open to the possibility in contexts where such makes sense.

    Grant borrows, in effect, from:

    ❝Do the best you can until you know better. Then when you know better… do better!❞

    ~ Maya Angelou

    So, not so much undercutting the principles we hold dear, and instead rather making sure they stand on firm foundations.

    All in all, a thought-provokingly inspiring read!
