It’s Q&A Day at 10almonds!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Could you do a series on mens health? Testosterone boosters. Libido? What works what doesnt? Also could you discuss prostate health and what supplements, meds, foods or protocols work to relieve symptoms of bph❞
We could indeed! We’ll be sure to write more, but while you’re waiting, you might like to read our main feature from a while back:
Too Much Or Too Little Testosterone?
…as it does include a lot about the use of a supplement that helps against Benign Prostatic Hyperplasia, with performance comparable to the most common drug prescribed for such.
And since (like that drug) it’s a 5α-reductase inhibitor (meaning it works by blocking the conversion of testosterone to DHT), this means it helps against prostate problems (and also, incidentally, male pattern hair loss) without reducing overall testosterone levels. In fact, because less testosterone will be converted to DHT, you’ll actually (all other things being equal) end up with slightly higher free testosterone levels.
❝My BMI is fine, but my waist is too big. What do I do about that? I am 5′ 5″ tall and 128 pounds and 72 years old.❞
It’s hard to say without knowing about your lifestyle (and hormones, for that matter)! But, extra weight around the middle in particular is often correlated with high levels of cortisol, so you might find this of benefit:
Lower Your Cortisol! (Here’s Why & How)
❝Is there anything special that might help someone with Tourette’s syndrome?❞
There are of course a lot of different manifestations of Tourette’s syndrome, and some people’s tics may be far more problematic to themselves and/or others, while some may be quite mild and just something to work around.
It’s an interesting topic for sure, so we’ll perhaps do a main feature (probably also covering the related-and-sometimes-overlapping OCD umbrella rather than making it hyperspecific to Tourette’s), but meanwhile, you might consider some of these options:
- Deep Brain Stimulation (DBS)
- Medications/ Pharmacology
- Comprehensive Behavioral Intervention for Tics (CBIT)
- Speech Therapies
❝Natural solutions for osteoarthritis. Eg. Rosehip tea, dandelion root tea. Any others??? What foods should I absolutely leave alone?❞
We’ll do a main feature on arthritis (in both its main forms) someday soon, but meanwhile, we recommend eating for good bone/joint health and against inflammation. To that end, you might like these main features we did on those topics:
- We Are Such Stuff As Fish Are Made Of (collagen for bone and joint health)
- The Bare-Bones Truth About Osteoporosis (eating for bone health generally)
- Keep Inflammation At Bay (dietary tips for minimizing inflammation—also, our all-time most popular article to date!)
Of these, probably the last one is the most critical, and also will have the speediest effects if implemented.
We turn the tables and ask you a question!
We’ll then talk about this tomorrow:

You Are Not Broken – by Dr. Kelly Casperson
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.
Many women express “I think I’m broken down there”, and it turns out simply that neither they nor their partners had the right knowledge, that’s all. The good news is: bedroom competence is an entirely learnable skill!
Dr. Casperson is a urologist, and over the years has expanded her work into all things pelvic, including the relevant use of both systemic and topical hormones (as in, hormones to increase overall blood serum levels of that hormone, like most HRT, and also, creams and lotions to increase levels of a given hormone in one particular place).
However, this is not 200 pages to say “take hormones”. Rather, she covers many areas of female sexual health and wellbeing, including yes, simply pleasure. From the physiological to the psychological, Dr. Casperson talks the reader through avoiding blame games and “getting out of your head and into your body”.
Bottom line: if you (or a loved one) are one of the many women who have doubts about being entirely correctly set up down there, then this book is definitely for you.

How anti-vaccine figures abuse data to trick you
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 anti-vaccine movement is nearly as old as vaccines themselves. For as long as humans have sought to harness our immune system’s incredible ability to recognize and fight infectious invaders, critics and conspiracy theorists have opposed these efforts.
Anti-vaccine tactics have advanced since the early days of protesting “unnatural” smallpox inoculation, and the rampant abuse of scientific data may be the most effective strategy yet.
Here’s how vaccine opponents misuse data to deceive people, plus how you can avoid being manipulated.
Misappropriating raw and unverified safety data
Perhaps the oldest and most well-established anti-vaccine tactic is the abuse of data from the federal Vaccine Adverse Event Reporting System, or VAERS. The Centers for Disease Control and Prevention and the Food and Drug Administration maintain VAERS as a tool for researchers to detect early warning signs of potential vaccine side effects.
Anyone can submit a VAERS report about any symptom experienced at any point after vaccination. That does not mean that these symptoms are vaccine side effects.
VAERS was not designed to determine if a specific vaccine caused a specific adverse event. But for decades, vaccine opponents have misinterpreted, misrepresented, and manipulated VAERS data to convince people that vaccines are dangerous.
Anyone relying on VAERS to draw conclusions about vaccine safety is probably trying to trick you. It isn’t possible to determine from VAERS data alone if a vaccine caused a specific health condition.
VAERS isn’t the only federal data that vaccine opponents abuse. Originally created for COVID-19 vaccines, V-safe is a vaccine safety monitoring system that allows users to report—via text message surveys—how they feel and any health issues they experience up to a year after vaccination. Anti-vaccine groups have misrepresented data in the system, which tracks all health experiences, whether or not they are vaccine-related.
The U.S. Department of Defense’s Defense Medical Epidemiology Database (DMED) has also become a target of anti-vaccine misinformation. Vaccine opponents have falsely claimed that DMED data reveals massive spikes in strokes, heart attacks, HIV, cancer, and blood clots among military service members since the COVID-19 vaccine rollout. The spike was due to an updated policy that corrected underreporting in the previous years
Misrepresenting legitimate studies
A common tactic vaccine opponents use is misrepresenting data from legitimate sources such as national health databases and peer-reviewed studies. For example, COVID-19 vaccines have repeatedly been blamed for rising cancer and heart attack rates, based on data that predates the pandemic by decades.
A prime example of this strategy is a preliminary FDA study that detected a slight increase in stroke risk in older adults after a high-dose flu vaccine alone or in combination with the bivalent COVID-19 vaccine. The study found no “increased risk of stroke following administration of the COVID-19 bivalent vaccines.”
Yet vaccine opponents used the study to falsely claim that COVID-19 vaccines were uniquely harmful, despite the data indicating that the increased risk was almost certainly driven by the high-dose flu vaccine. The final peer-reviewed study confirmed that there was no elevated stroke risk following COVID-19 vaccination. But the false narrative that COVID-19 vaccines cause strokes persists.
Similarly, the largest COVID-19 vaccine safety study to date confirmed the extreme rarity of a few previously identified risks. For weeks, vaccine opponents overstated these rare risks and falsely claimed that the study proves that COVID-19 vaccines are unsafe.
Citing preprint and retracted studies
When a study has been retracted, it is no longer considered a credible source. A study’s retraction doesn’t deter vaccine opponents from promoting it—it may even be an incentive because retracted papers can be held up as examples of the medical establishment censoring so-called “truthtellers.” For example, anti-vaccine groups still herald Andrew Wakefield nearly 15 years after his study falsely linking the measles, mumps, and rubella (MMR) vaccine to autism was retracted for data fraud.
The COVID-19 pandemic brought the lasting impact of retracted studies into sharp focus. The rush to understand a novel disease that was infecting millions brought a wave of scientific publications, some more legitimate than others.
Over time, the weaker studies were reassessed and retracted, but their damage lingers. A 2023 study found that retracted and withdrawn COVID-19 studies were cited significantly more frequently than valid published COVID-19 studies in the same journals.
In one example, a widely cited abstract that found that ivermectin—an antiparasitic drug proven to not treat COVID-19—dramatically reduced mortality in COVID-19 patients exemplifies this phenomenon. The abstract, which was never peer reviewed, was retracted at the request of its authors, who felt the study’s evidence was weak and was being misrepresented.
Despite this, the study—along with the many other retracted ivermectin studies—remains a touchstone for proponents of the drug that has shown no effectiveness against COVID-19.
In a more recent example, a group of COVID-19 vaccine opponents uploaded a paper to The Lancet’s preprint server, a repository for papers that have not yet been peer reviewed or published by the prestigious journal. The paper claimed to have analyzed 325 deaths after COVID-19 vaccination, finding COVID-19 vaccines were linked to 74 percent of the deaths.
The paper was promptly removed because its conclusions were unsupported, leading vaccine opponents to cry censorship.
Applying animal research to humans
Animals are vital to medical research, allowing scientists to better understand diseases that affect humans and develop and screen potential treatments before they are tested in humans. Animal research is a starting point that should never be generalized to humans, but vaccine opponents do just that.
Several animal studies are frequently cited to support the claim that mRNA COVID-19 vaccines are dangerous during pregnancy. These studies found that pregnant rats had adverse reactions to the COVID-19 vaccines. The results are unsurprising given that they were injected with doses equal to or many times larger than the dose given to humans rather than a dose that is proportional to the animal’s size.
Similarly, a German study on rat heart cells found abnormalities after exposure to mRNA COVID-19 vaccines. Vaccine opponents falsely insinuated that this study proves COVID-19 vaccines cause heart damage in humans and was so universally misrepresented that the study’s author felt compelled to dispute the claims.
The author noted that the study used vaccine doses significantly higher than those administered to humans and was conducted in cultured rat cells, a dramatically different environment than a functioning human heart.
How to avoid being misled
The internet has empowered vaccine opponents to spread false information with an efficiency and expediency that was previously impossible. Anti-vaccine narratives have advanced rapidly due to the rampant exploitation of valid sources and the promotion of unvetted, non-credible sources.
You can avoid being tricked by using multiple trusted sources to verify claims that you encounter online. Some examples of credible sources are reputable public health entities like the CDC and World Health Organization, personal health care providers, and peer-reviewed research from experts in fields relevant to COVID-19 and the pandemic.

Yes, you still need to use sunscreen, despite what you’ve heard on TikTok
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.
Summer is nearly here. But rather than getting out the sunscreen, some TikTokers are urging followers to chuck it out and go sunscreen-free.
They claim it’s healthier to forgo sunscreen to get the full benefits of sunshine.
Here’s the science really says.
Karolina Grabowska/Pexels How does sunscreen work?
Because of Australia’s extreme UV environment, most people with pale to olive skin or other risk factors for skin cancer need to protect themselves. Applying sunscreen is a key method of protecting areas not easily covered by clothes.
Sunscreen works by absorbing or scattering UV rays before they can enter your skin and damage DNA or supportive structures such as collagen.
When UV particles hit DNA, the excess energy can damage our DNA. This damage can be repaired, but if the cell divides before the mistake is fixed, it causes a mutation that can lead to skin cancers.
The energy from a particle of UV (a photon) causes DNA strands to break apart and reconnect incorrectly. This causes a bump in the DNA strand that makes it difficult to copy accurately and can introduce mutations. NASA/David Herring The most common skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common, but is the most likely to spread around the body; this process is called metastasis.
Two in three Australians will have at least one skin cancer in their lifetime, and they make up 80% of all cancers in Australia.
Around 99% of skin cancers in Australia are caused by excessive exposure to UV radiation.
Excessive exposure to UV radiation also affects the appearance of your skin. UVA rays are able to penetrate deep into the skin, where they break down supportive structures such as elastin and collagen.
This causes signs of premature ageing, such as deep wrinkling, brown or white blotches, and broken capillaries.
Sunscreen can help prevent skin cancers
Used consistently, sunscreen reduces your risk of skin cancer and slows skin ageing.
In a Queensland study, participants either used sunscreen daily for almost five years, or continued their usual use.
At the end of five years, the daily-use group had reduced their risk of squamous cell carcinoma by 40% compared to the other group.
Ten years later, the daily use group had reduced their risk of invasive melanoma by 73%
Does sunscreen block the health-promoting properties of sunlight?
The answer is a bit more complicated, and involves personalised risk versus benefit trade-offs.
First, the good news: there are many health benefits of spending time in the sun that don’t rely on exposure to UV radiation and aren’t affected by sunscreen use.
Sunscreen only filters UV rays, not all light. Ron Lach/Pexels Sunscreen only filters UV rays, not visible light or infrared light (which we feel as heat). And importantly, some of the benefits of sunlight are obtained via the eyes.
Visible light improves mood and regulates circadian rhythm (which influences your sleep-wake cycle), and probably reduces myopia (short-sightedness) in children.
Infrared light is being investigated as a treatment for several skin, neurological, psychiatric and autoimmune disorders.
So what is the benefit of exposing skin to UV radiation?
Exposing the skin to the sun produces vitamin D, which is critical for healthy bones and muscles.
Vitamin D deficiency is surprisingly common among Australians, peaking in Victoria at 49% in winter and being lowest in Queensland at 6% in summer.
Luckily, people who are careful about sun protection can avoid vitamin D deficiency by taking a supplement.
Exposing the skin to UV radiation might have benefits independent of vitamin D production, but these are not proven. It might reduce the risk of autoimmune diseases such as multiple sclerosis or cause release of a chemical that could reduce blood pressure. However, there is not enough detail about these benefits to know whether sunscreen would be a problem.
What does this mean for you?
There are some benefits of exposing the skin to UV radiation that might be blunted by sunscreen. Whether it’s worth foregoing those benefits to avoid skin cancer depends on how susceptible you are to skin cancer.
If you have pale skin or other factors that increase you risk of skin cancer, you should aim to apply sunscreen daily on all days when the UV index is forecast to reach 3.
If you have darker skin that rarely or never burns, you can go without daily sunscreen – although you will still need protection during extended times outdoors.
For now, the balance of evidence suggests it’s better for people who are susceptible to skin cancer to continue with sun protection practices, with vitamin D supplementation if needed.

Unfuck Your Brain – by Dr. Faith Harper
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.
This book takes a trauma-informed care approach, which is relatively novel in the mental health field and it’s quickly becoming the industry standard because of its effectiveness.
The basic premise of trauma-informed care is that you had a bad experience (possibly even more than one—what a thought!) and that things that remind you of that will tend to prompt reactivity from you in a way that probably isn’t healthy. By identifying each part of that process, we can then interrupt it, much like we might with CBT (the main difference being that CBT, for all its effectiveness, tends to assume that the things that are bothering you are not true, while TIC acknowledges that they might well be, and that especially historically, they probably were).
A word of warning: if something that triggers a trauma-based reactivity response in you is people swearing, then this book will either cure you by exposure therapy or leave you a nervous wreck, because it’s not just the title; Dr. Harper barely gets through a sentence without swearing. It’s a lot, even by this (European) reviewer’s standards (we’re a lot more relaxed about swearing over here, than people tend to be in America).
On the other hand, something that Dr. Harper excels at is actually explaining stuff very well. So while it sometimes seems like she’s “trying too hard” style-wise in terms of being “not like other therapists”, in her defence she’s nevertheless a very good writer; she knows her stuff, and knows how to communicate it clearly.
Bottom line: if you don’t mind a writer who swears more than 99% of soldiers, then this book is an excellent how-to guide for self-administered trauma-informed care.

How the stress of playing chess can be fatal
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 death of a chess player in the middle of a match at the world’s most prestigious competition may have shocked those who view the game as a relaxing pastime. Kurt Meier, 67, collapsed during his final match in the tournament and died in hospital later that day. But chess, like any other game or sport, can lead to an immense amount of stress, which can be bad for a competitor’s physical health too.
We tend to associate playing sport or games with good health and well-being. And there are a countless number of studies showing playing games has an association with feeling happier. While this argument is true for recreational players, the story can be different for the elite, where success and failure are won and lost by the finest margins and where winning can mean funding and a future, and losing can mean poverty and unemployment. If this is the case, can being successful at a sport or game actually be bad for you?
Competitive anxiety
Elite competition can be stressful because the outcome is so important to the competitors. We can measure stress using a whole range of physiological indicators such as heart rate and temperature, and responses such as changes in the intensity of our emotions.
Emotions provide a warning of threat. So if you feel that achieving your goal is going to be difficult, then expect to feel intense emotions. The leading candidate that signals we are experiencing stress is anxiety, characterised by thoughts of worry, fears of dread about performance, along with accompanying physiological responses such as increased heart rate and sweaty palms. If these symptoms are experienced regularly or chronically, then this is clearly detrimental to health.
This stress response is probably not restricted to elite athletes. Intense emotions are linked to trying to achieve important goals and while it isn’t the only situation where it occurs, it is just very noticeable in sport.
The causes of stress
It makes more sense to focus on what the causes of stress are rather than where we experience it. The principle is that the more important the goal is to achieve, then the greater the propensity for the situation to intensify emotions.
Emotions intensify also by the degree of uncertainty and competing, at whatever level of a sport, is uncertain when the opposition is trying its hardest to win the contest and also has a motivation to succeed. The key point is that almost all athletes at any level can suffer bouts of stress, partly due to high levels of motivation.
A stress response is also linked to how performance is judged and reported. Potentially stressful tasks tend to be ones where performance is public and feedback is immediate. In chess – as with most sporting contests – we see who the winner is and can start celebrating success or commiserating failure as soon as the game is over.
There are many tasks which have similar features. Giving a speech in public, taking an academic examination, or taking your driving test are all examples of tasks that can illicit stress. Stress is not restricted to formal tasks but can also include social tasks. Asking a potential partner for a date, hand in marriage, and meeting the in-laws for the first time can be equally stressful.
Winning a contest or going on a date relate to higher-order goals about how we see ourselves. If we define ourselves as “being a good player” or “being attractive or likeable” then contrasting information is likely to associate with unpleasant emotions. You will feel devastated if you are turned down when asking someone out on a date, for instance, and if this was repeated, it could lead to reduced self-esteem and depression.
The key message here is to recognise what your goals are and think about how important they are. If you want to achieve them with a passion and if the act of achieving them leads to intense and sometimes unwanted emotions, then it’s worth thinking about doing some work to manage these emotions.

‘Disease X’: What it is (and isn’t)
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.
What you need to know
- In January 2024, the World Economic Forum hosted an event called Preparing for Disease X to discuss strategies to improve international pandemic response.
- Disease X is a term used in epidemiology to refer to potential disease threats. It is not a real disease or a global conspiracy.
- Preparation to prevent and respond to future pandemics is a necessary part of global health to keep us all safer.
During the World Economic Forum’s 54th annual meeting in Davos, Switzerland, global health experts discussed ways to strengthen health care systems in preparation for future pandemics. Conspiracy theories quickly began circulating posts about the event and the fictional disease at its center, so-called Disease X.
What is Disease X?
In 2018, the World Health Organization added Disease X to its list of Blueprint Priority Diseases that are public health risks. But, unlike the other diseases on the list, Disease X doesn’t exist. The term represents a hypothetical human disease capable of causing a pandemic. Although experts don’t know what the next Disease X will be, they can make educated guesses about where and how it may emerge—and how we can prepare for it.
Why are we hearing about Disease X now?
COVID-19 has been the deadliest infectious disease outbreak of the 21st century. It’s also an example of a Disease X: a previously unknown pathogen that spreads rapidly around the world, claiming millions of lives.
When the WEF hosted a panel of experts to discuss Disease X, it was the first exposure that many people had to a concept that global health experts have been discussing since 2018.
Even before the routine pandemic preparedness event took place, online conspiracy theorists began circulating false claims that those discussing and preparing for Disease X had sinister motives, underscoring how widespread distrust of global health entities has become in the wake of the COVID-19 pandemic.
Why does Disease X matter?
Epidemiologists use concepts like Disease X to plan for future outbreaks and avoid the mistakes of past outbreaks. The COVID-19 pandemic and the recent non-endemic outbreak of mpox highlight the importance of global coordination to efficiently prevent and respond to disease outbreaks.
Pandemics are inevitable, but the scale of their destruction doesn’t have to be. Major disease outbreaks are likely to become more frequent due to the impacts of climate change. Preparing for a pandemic now helps ensure that the world is better equipped to handle the next one.
