Ikigai is the Japanese term for what in English we often call “raison d’être”… in French, because English is like that.
But in other words: ikigai is one’s purpose in life, one’s reason for living.
The authors of this work spend some chapters extolling the virtues of finding one’s ikigai, and the health benefits that doing so can convey. It is, quite clearly, an important and relevant factor.
The rest of the book goes beyond that, though, and takes a holistic look at why (and how) healthy longevity is enjoyed by:
- Japanese people in general,
- Okinawans in particular,
- Residents of Okinawa’s “blue zone” village with the highest percentage of supercentenarians, most of all.
Covering considerations from ikigai to diet to small daily habits to attitudes to life, we’re essentially looking at a blueprint for healthy longevity.
For a book whose title and cover suggests a philosophy-heavy content, there’s a lot of science in here too, by the way! From microbiology to psychiatry to nutrition science to cancer research, this book covers all bases.
In short: this book gives a lot of good science-based suggestions for adjustments we can make to our lives, without moving to an Okinawan village!

The Missing Links – by Drs Phillip Meade & Laura Gallagher
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 looks at what goes wrong in projects, why it goes wrong, and how to fill in those “missing links” so that we don’t make the same mistakes that failed projects before us have made.
Using the Columbia crash (and NASA’s subsequent investigation and organizational overhaul) as an example, Drs Meade and Gallagher take us through the steps to apply NASA’s resultant model to our own projects.
The book is aimed squarely at business management, but the lessons within are applicable to any kind of project management, whether the project in question is a Fortune 500 merger or a new patio.
Bottom line is as per the blurb: “you don’t have to be a rocket scientist to apply this model to your organization to create a culture of accountability, inclusivity, and productivity.”

How (And Why) To Train Your Pre-Frontal Cortex

Dr. Chapman’s Keys For Mental Focus
This is Dr. Sandra Chapman; she’s a cognitive neuroscientist, on a mission to, in her words, further our understanding of:
- what makes the brain stronger, faster and last longer
- what enhances human cognitive capacity, and
- what enhances the underlying brain systems across the lifespan.
To this end, she’s also the founder and Chief Director of the Center For Brain Health, where she has worked on her mission for the past 25 years (clocking up hundreds of peer-reviewed publications to her name), as well as being a professor of Behavioral and Brain Sciences at UT Dallas.
What does she want us to know?
Get your brain into gear
When it comes to your brainpower, it is “use it or lose it”, but it is also perfectly possible to use it and lose it.
Why?
Very often, what we are using our brains for is high-strain, low-yield stuff, such as multitasking, overthinking, or overthinking while multitasking. And to make it worse, we often do it without sufficient rest.
This is the equivalent of owning a Ferrari but trying to drive it in second and third gear at once by switching between the two as rapidly as possible. And doing that for 18 hours each day.
Suffice it to say, you’ll be going nowhere quickly.
An alternative “use” of brainpower is low-strain, low-yield stuff, such as having to pay close attention to a boring conversation. It’s enough to stop your mind from doing anything else, but not enough to actually stimulate you.
This is the equivalent of owning a Ferrari but keeping it idling. The wear and tear is minimal this time, but you’re not actually going anywhere either.
Better, of course, are the other two quadrants:
- low-strain, high-yield: consistently using our brain in relatively non-taxing ways that encourage its development
- high-strain, high-yield: here the Ferrari metaphor definitely fails, because unlike cars, our bodies (including our brains) are machines that benefit from judicious regular progressive overloading (but just by a bit, and with adequate recovery time between overloads).

How to do the “low-strain, low-yield” part
When it comes to “what’s the most important part of the brain to help in the face of cognitive decline?” the usual answer is either to focus on memory (hippocampi) or language (various parts, but for example Wernicke’s area and Broca’s area), since people most fear losing memory, and language is very important both socially and practically.
Those are indeed critical, and we at 10almonds stand by them, but Dr. Chapman (herself having originally trained as speech and language pathologist!) makes a strong case for adding a third brain part to the list.
Specifically, she advocates for strengthening the pre-frontal cortex, which is responsible for inhibition, task-switching, working memory, and cognitive flexibility. If that seems like a lot, do remember it’s a whole cortex and not one of the assorted important-but-small brain bits we mentioned above.
How? She has developed training programs for this, based on what she calls Strategic Memory Advanced Reasoning Tactics (SMART), to support support attention, planning, judgment and emotional management.
You can read more about those programs here:
Center For Brain Health | Our Programs
Participation in those is mostly not free, however, if you join their…
Center For Brain Health | BrainHealth Project
…then they will periodically invite you to join pilot programs, research programs, and the like, which will either be free or they-pay-you affairs—because this is how science is done, and you can read about yourself (anonymized, of course) later in peer-reviewed papers of the kind we often cite here.
If you’re not interested in any of that though, we will say that according to Dr. Chapman, the keys are:
Inhibition: be conscious of this function of your brain, and develop it. This is the function of your brain that stops you from making mistakes—or put differently: stops you from saying/doing something stupid.
Switching: do this consciously; per “I am now doing this task, now I am switching to this other task”, rather than doing the gear-grinding thing we discussed earlier
Working memory: this is effectively your brain’s RAM. Unlike the RAM of a computer (can be enhanced by adding another chip or replacing with a bigger chip), our brain’s RAM can be increased by frequent use, and especially by judicious use of progressive overloading (with rests between!) which we’ll discuss in the high-strain, high-yield section.
Flexibility: this is about creative problem-solving, openness to new ideas, and curiosity

How to do the “high-strain, high-yield” part
Delighting this chess-playing writer, Dr. Chapman recommends chess. Although, similar games such as go (a Chinese game that looks simpler than chess but actually requires more calculation) work equally well too.
Why?
Games like chess and go cause structural changes that are particularly helpful, in terms of engaging in such foundational tasks as learning, abstract reasoning, problem-solving and self-control:
Chess Practice as a Protective Factor in Dementia
Basically, it checks (so to speak) a lot of boxes, especially for the pre-frontal cortex. Some notes:
- Focusing on the game is required for brain improvement; simply pushing wood casually will not do it. Ideally, calculating several moves ahead will allow for strong working memory use (because to calculate several moves ahead, one will have to hold increasingly many possible positions in the mind while doing so).
- The speed of play must be sufficiently slow as to allow not only for thinking, but also for what in chess is called “blunder-checking”, in other words, having decided on one’s move, pausing to consider whether it is a mistake, and actively trying to find evidence that it is. This is the crucial “inhibition habit”, and when one does it reflexively, one will make fewer mistakes. Tying this to dementia, see for example how one of the common symptoms of dementia is falling for scams that one wouldn’t have previously. How did cognitive decline make someone naïve? It didn’t, per se; it just took away their ability to, having decided what to do, pause to consider whether it was a mistake, and actively trying to find evidence that it is.
- That “conscious switching” that we talked about, rather than multitasking? In chess, there is a difference between strategy and tactics. Don’t worry about what that difference is for now (learn it if you want to take up chess), but know that strong players will only strategize while it is their opponent’s turn, and only calculate (tactics) while it is their own turn. It’s very tempting to flit constantly between one and the other, but chess requires players to have the mental discipline be able to focus on one task or the other and stick with that task until it’s the appointed time to switch.
If you feel like taking up chess, this site (and related app, if you want it) is free (it’s been funded by voluntary donations for a long time now) and good and even comes with free tuition and training tools: LiChess.org
Here’s another site that this writer (hi, it’s me) personally uses—it has great features too, but many are paywalled (I’m mostly there just because I’ve been there nearly since its inception, so I’m baked into the community now): Chess.com

Will there soon be a cure for HIV?
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.
Human immunodeficiency virus, or HIV, is a chronic health condition that can be fatal without treatment. People with HIV can live healthy lives by taking antiretroviral therapy (ART), but this medication must be taken daily in order to work, and treatment can be costly. Fortunately, researchers believe a cure is possible.
In July, a seventh person was reportedly cured of HIV following a 2015 stem cell transplant for acute myeloid leukemia. The patient stopped taking ART in 2018 and has remained in remission from HIV.
Read on to learn more about HIV, the promise of stem cell transplants, and what other potential cures are on the horizon.
What is HIV?
HIV infects and destroys the immune system’s cells, making people more susceptible to infections. If left untreated, HIV will severely impair the immune system and progress to acquired immunodeficiency syndrome (AIDS). People living with untreated AIDS typically die within three years.
People with HIV can take ART to help their immune systems recover and to reduce their viral load to an undetectable level, which slows the progression of the disease and prevents them passing the virus to others.
How can stem cell transplants cure HIV?
Several people have been cured of HIV after receiving stem cell transplants to treat leukemia or lymphoma. Stem cells are produced by the spongy tissue located in the center of some bones, and they can turn into new blood cells.
A mutation on the CCR5 gene prevents HIV from infecting new cells and creates resistance to the virus, which is why some HIV-positive people have received stem cells from donors carrying this mutation. (One person was reportedly cured of HIV after receiving stem cells without the CCR5 mutation, but further research is needed to understand how this occurred.)
Despite this promising news, experts warn that stem cell transplants can be fatal, so it’s unlikely this treatment will be available to treat people with HIV unless a stem cell transplant is needed to treat cancer. People with HIV are at an increased risk for blood cancers, such as Hodgkin lymphoma and non-Hodgkin lymphoma, which stem cell transplants can treat.
Additionally, finding compatible donors with the CCR5 mutation who share genetic heritage with patients of color can be challenging, as donors with the mutation are typically white.
What are other potential cures for HIV?
In some rare cases, people who started ART shortly after infection and later stopped treatment have maintained undetectable levels of HIV in their bodies. There have also been some people whose bodies have been able to maintain low viral loads without any ART at all.
Researchers are studying these cases in their search for a cure.
Other treatment options researchers are exploring include:
- Gene therapy: In addition to stem cell transplants, gene therapy for HIV involves removing genes from HIV particles in patients’ bodies to prevent the virus from infecting other cells.
- Immunotherapy: This treatment is typically used in cancer patients to teach their immune systems how to fight off cancer. Research has shown that giving some HIV patients antibodies that target the virus helps them reach undetectable levels of HIV without ART.
- mRNA technology: mRNA, a type of genetic material that helps produce proteins, has been used in vaccines to teach cells how to fight off viruses. Researchers are seeking a way to send mRNA to immune system cells that contain HIV.
When will there be a cure for HIV?
The United Nations and several countries have pledged to end HIV and AIDS by 2030, and a 2023 UNAIDS report affirmed that reaching this goal is possible. However, strategies to meet this goal include HIV prevention and improving access to existing treatment alongside the search for a cure, so we still don’t know when a cure might be available.
How can I find out if I have HIV?
You can get tested for HIV from your primary care provider or at your local health center. You can also purchase an at-home HIV test from a drugstore or online. If your at-home test result is positive, follow up with your health care provider to confirm the diagnosis and get treatment.
For more information, talk to your health care provider.

Wholewheat Bread vs Seeded White – 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 wholewheat bread to seeded bread, we picked the wholewheat.
Why?
First, we will acknowledge that this is a false dichotomy; it is possible to have seeded wholewheat bread. However, it is very common to have wholewheat bread that isn’t seeded, and white bread that is seeded. So, it’s important to be able to decide which is the healthier option, since very often, this false dichotomy is what’s on offer.
We will also advise checking labels (or the baker, if getting from a bakery) to ensure that visibly brown bread is actually wholewheat, and not just dyed brown with caramel coloring or such (yes, that is a thing that some companies do).
Now, as for why we chose the wholewheat over the seeded white…
In terms of macronutrients, wholewheat bread has (on average; individual breads may vary of course) has 2x the protein and a lot more fiber.
Those seeds in seeded bread? They just aren’t enough to make a big impact on the overall nutritional value of the bread in those regards. Per slice, you are getting, what, 10 seeds maybe? This is not a meaningful dietary source of much.
Seeded bread does have proportionally more healthy fats, but the doses are still so low as to make it not worth the while; it just looks like a lot of expressed as a percentage of comparison, because of the wholewheat bread has trace amounts, and the seeded bread has several times those trace amounts, it’s still a tiny amount. So, we’d recommend looking to other sources for those healthy fats.
Maybe dip your bread, of whatever kind, into extra virgin olive oil, for example.
Wholewheat bread of course also has a lower glycemic index. Those seeds in seeded white bread don’t really slow it down at all, because they’re not digested until later.

❝Loved the info on nuts; of course I always eat pecans, which didn’t make the list of healthy nuts!❞
Dear subscriber, pardon the paraphrase of your comment—somehow it got deleted and now exists only in this writer’s memory. However, to address it:
Pecans are great too! We can’t include everything in every article (indeed, we got another feedback the same day saying the article was too long), but we love when you come to us with stuff for us to look at and write about (seriously, writer here: the more you ask, the easier it makes my job), so let’s talk pecans for a moment:
Pecans would have been number six on our list if we’d have written more!
Like many nuts, they’ve an abundance of healthy fats, fiber, vitamins, and minerals.
They’re particularly good for zinc, which is vital for immune function, healing (including normal recovery after normal exercise), and DNA synthesis (so: anti-aging).
Pecans are also great for reducing LDL (“bad” cholesterol) and triglycerides (which are also bad for heart health); check it out:

I thoroughly enjoy your daily delivery. I’d love to see one for teens too!
That’s great to hear! The average age of our subscribers is generally rather older, but it’s good to know there’s an interest in topics for younger people. We’ll bear that in mind, and see what we can do to cater to that without alienating our older readers!
That said: it’s never too soon to be learning about stuff that affects us when we’re older—there are lifestyle factors at 20 that affect Alzheimer’s risk at 60, for example (e.g. drinking—excessive drinking at 20* is correlated to higher Alzheimer’s risk at 60).
*This one may be less of an issue for our US readers, since the US doesn’t have nearly as much of a culture of drinking under 21 as some places. Compare for example with general European practices of drinking moderately from the mid-teens, or the (happily, diminishing—but historically notable) British practice of drinking heavily from the mid-teens.
