Four Thousand Weeks – by Oliver Burkeman

This is not, strictly speaking, a time management book. It’s more a “contemplating mortality and making things count while still doing the necessaries”.
Burkeman’s premise is that we get around 4,000 weeks of life, on average. If we live to 120, it’s more like 6,200. Unlucky souls may have to do the best they can with 1,000 or so.
The book is thought-provoking; consider:
- how was your last week?
- how will your next week be?
- what if it were your last?
Of course, we cannot necessarily liquidate all our assets and spend next week burning out in style, because then the following week comes. So, what’s the solution?
That’s something Burkeman lays out over the course of the book, with key ideas including passion projects and figuring out what can be safely neglected, but there’s far more there than we could sum up here.
Bottom line: if you ever find yourself struggling to balance what is expected of you with what is of value to you, this book can help you get the most out of your choices.

Stop Cancer 20 Years Ago

Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.

Why We Get Fat: And What to Do About It – by Gary Taubes
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.
We’ve previously reviewed Taubes’ “The Case Against Sugar“. What does this one bring differently?
Mostly, it’s a different focus. Unsurprisingly, Taubes’ underlying argument is the same: sugar is the biggest dietary health hazard we face. However, this book looks at it specifically through the lens of weight loss, or avoiding weight gain.
Taubes argues for low-carb in general; he doesn’t frame it specifically as the ketogenic diet here, but that is what he is advocating. However, he also acknowledges that not all carbs are created equal, and looks at several categories that are relatively better or worse for our insulin response, and thus, fat management.
If the book has a fault it’s that it does argue a bit too much for eating large quantities of meat, based on Weston Price’s outdated and poorly-conducted research. However, if one chooses to disregard that, the arguments for a low-carb diet for weight management remain strong.
Bottom line: if you’d like to cut some fat without eating less (or exercising more), this book offers a good, well-explained guide for doing so.

Tips For Avoiding/Managing Rheumatoid Arthritis
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.
Avoiding/Managing Rheumatoid Arthritis
Arthritis is the umbrella term for a cluster of joint diseases involving inflammation of the joints, hence “arthr-” (joint) “-itis” (suffix used to denote inflammation). These are mostly, but not all, autoimmune diseases, in which the body’s immune system mistakenly attacks our own joints.
Inflammatory vs Non-Inflammatory Arthritis
Arthritis is broadly divided into inflammatory arthritis and non-inflammatory arthritis.
You may be wondering: how does one get non-inflammatory inflammation of the joints?
The answer is, in “non-inflammatory” arthritis, such as osteoarthritis, the damage comes first (by general wear-and-tear) and inflammation generally follows as part of the symptoms, rather than the cause. So the name can be a little confusing. In the case of osteo- and other “non-inflammatory” forms of arthritis, you definitely still want to keep your inflammation at bay as best you can, but it’s not as absolutely critical a deal as it is for “inflammatory” forms of arthritis.
We’ll tackle the beast that is osteoarthritis another day, however.
Today we’re going to focus on…
Rheumatoid Arthritis
This is the most common of the autoimmune forms of arthritis. Some quick facts:
- It affects a little under 1% of the global population, but the older we get, the more likely it becomes
- Early onset of rheumatoid arthritis is most likely to show up around the age of 50 (but it can show up at any age)
- However, incidence (not onset) of rheumatoid arthritis peaks in the 70s age bracket
- It is 2–4 times more common in women than in men
- Approximately one third of people stop work within two years of its onset, and this increases thereafter.
Well, that sounds gloomy.
Indeed it’s not fun. There’s a lot of stiffness and aching of joints (often with swelling too), loss of joint function can be common, and then there are knock-on effects like fatigue, weakness, and loss of appetite.
Beyond that it’s an autoimmune disorder, its cause is not known, and there is no known cure.
Is there any good news?
If you don’t have rheumatoid arthritis at the present time, you can reduce your risk factors in several ways:
- Having an anti-inflammatory diet. Get plenty of fiber, greens, and berries. Fatty fish is great too, as are oily nuts. On the other side of things, high consumption of salt, sugar, alcohol, and red meat are associated with a greater risk of developing rheumatoid arthritis.
- Not smoking. Smoking is bad for pretty much everything, including your chances of developing rheumatoid arthritis.
- Not being obese. This one may be more a matter of correlation than causation, because of the dietary factors (if one eats an anti-inflammatory diet, obesity is less likely), but the association is there.
There are other risk factors that are harder to control, such as genetics, age, sex, and having a mother who smoked.
See: Genetic and environmental risk factors for rheumatoid arthritis
What if I already have rheumatoid arthritis?
If you already have rheumatoid arthritis, it becomes a matter of symptom management.
First, reduce inflammation any (reasonable) way you can. We did a main feature on this before, so we’ll just drop that again here:
Next, consider the available medications. Your doctor may or may not have discussed all of the options with you, so be aware that there are more things available than just pain relief. To talk about them all would require a whole main feature, so instead, here’s a really well-compiled list, along with explanations about each of them, up to date as of this year:
Rheumatoid Arthritis Medication List (And What They Do, And How)
Finally, consider other lifestyle adjustments to manage your symptoms. These include:
- Exercise—gently, though! You do not want to provoke a flare-up, but you do want to maintain your mobility as best you can. There’s a use-it-or-lose-it factor here. Swimming and yoga are great options, as is tai chi. You may want to avoid exercises that involve repetitive impacts to your joints, like running.
- Rest—while keeping mobility going. Get good sleep at night (this is important), but don’t make your bed your new home, or your mobility will quickly deteriorate.
- Hot & cold—both can help, and alternating them can reduce inflammation and stiffness by improving your body’s ability to respond appropriately to these stimuli rather than getting stuck in an inappropriate-response state of inflammation.
- Mobility aids—if it helps, it helps. Maybe you only need something during a flare-up, but when that’s the case, you want to be as gentle on your body as possible while keeping moving, so if crutches, handrails etc help, then by all means get them and use them.
- Go easy on the use of braces, splints, etc—these can offer short-term relief, but at a long term cost of loss of mobility. Only you can decide where to draw the line when it comes to that trade-off.

Pistachios vs Pine Nuts – 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 pistachios to pine nuts, we picked the pistachios.
Why?
First looking at the macros, pistachios have nearly 2x the protein while pine nuts have nearly 2x the fat. The fats are healthy in moderation (mostly polyunsaturated, a fair portion of monounsaturated, and a little saturated), but we’re going to value the protein content higher. Also, pistachios have approximately 2x the carbs, and/but nearly 3x the fiber. All in all, we’ll call this section a moderate win for pistachios.
When it comes to vitamins, pistachios have more of vitamins A, B1, B5, B6, B9, and C, while pine nuts have more of vitamins B2, B3, E, K, and choline. All in all, pistachios are scraping a 6:5 win here, or we could call it a tie if we want to value pine nuts’ vitamins more (due to the difference in how many foods each vitamin is found in, and thus the likelihood of having a deficiency or not).
In the category of minerals, pistachios have more calcium, copper, potassium, and selenium, while pine nuts have more iron, magnesium, manganese, and zinc. This would be a tie if we just call it 4:4, but what’s worth noting is that while both of these nuts are a good source of most of the minerals mentioned, pine nuts aren’t a very good source of calcium or selenium, so we’re going to declare this section a very marginal win for pistachios.
Adding up the moderate win, the scraped win, and the barely scraped win, all adds up to a win for pistachios. However, as you might have noticed, both are great so do enjoy both if you can!

The Biological Mind – by Dr. Alan Jasanoff

How special is our brain? According to Dr. Alan Jasanoff, it’s not nearly as special as we think it is.
In this work, he outlines the case for how we have collectively overstated the brain’s importance. That it’s just another organ like a heart or a kidney, and that who we are is as much a matter of other factors, as what goes on in our brain.
In this reviewer’s opinion, he overcorrects a bit. The heart and kidneys are very simple organs, as organs go. The brain is not. And while everything from our gut microbiota to our environment to our hormones may indeed contribute to what is us, our brain is one thing that can’t just be swapped out.
Nevertheless, this very well-written book can teach us a lot about everything else that makes us us, including many biological factors that many people don’t know about or consider.
Towards the end of the book, he switches into futurist speculation, and his speculation can be summed up as “we cannot achieve anything worthwhile in the future”.
Bottom line: if you’ve an interest in such things as how transplanting glial cells can give a 30% cognitive enhancement, and how a brain transplant wouldn’t result in the same us in a different body, this is the book for you.

A Cold Shower A Day Keeps The Doctor 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.
A Cold Shower A Day Keeps The Doctor Away?
This is Dutch extreme athlete Wim Hof, also known as “The Iceman”! He’s broken many world records mostly relating to the enduring the cold, for example:
- climbing Mount Kilimanjaro in shorts
- running a half-marathon above the Arctic Circle barefoot
- standing in a container completely covered with ice cubes for more than 112 minutes
You might not want to do yoga in your pyjamas on an iceberg, but you might like…
- better circulatory health
- reduced risk of stroke
- a boosted immune system
- healthier skin
- more energy and alertness
…and things like that. Wim Hof’s method is not just about extreme athletic achievements; most of what he does, the stuff that can benefit the rest of us, is much more prosaic.
The Wim Hof Method
For Wim Hof, three things are key:
- Breathing (See: Wim Hof Method Breathing Exercises)
- Commitment (See: How to Increase Willpower)
- Cold therapy (See: Benefits of Cold Therapy)
Today, we’re going to be focusing on the last one there.
What are the benefits of Cold Therapy?
Once upon a time, we didn’t have central heating, electric blankets, thermal underwear, and hot showers. In fact, once upon a time, we didn’t have houses or clothes. We used to be a lot more used to the elements! And while it’s all well and good to enjoy modern comforts, it has left our bodies lacking practice.
Practice at what? Most notably: vasodilation and vasoconstriction, in response to temperature changes. Either:
- vasodilation, because part of our body needs more blood to keep it warm and nourished, or
- vasoconstriction, because part of our body needs less blood running through it to get cooled down.
Switching between the two gives the blood vessels practice at doing it, and improves vascular muscle tone. If your body doesn’t get that practice, your blood vessels will be sluggish at making the change. This can cause circulation problems, which in turn have a big impact in many other areas of health, including:
- cardiovascular disease
- stroke risk
- mood instability
- nerve damage in extremities
On the flipside, if the blood vessels do get regular practice at dilating and constricting, you might enjoy lower risk of those things, and instead:
- improved immune response
- healthier skin
- better quality sleep
- more energy and alertness
- improved sexual performance/responsiveness
So, how to get that, without getting extreme?
As today’s title suggests, “a cold shower a day” is a great practice.
You don’t have to jump straight in, especially if you think your circulation and vascular responses might be a bit sluggish in the first instance. In fact, Wim Hof recommends:
- Week 1: Thirty seconds of cold water at the end of a warm shower each morning
- Week 2: One minute of cold water at the end of a warm shower each morning
- Week 3: A minute and a half of cold water at the end of a warm shower each morning
- Week 4: Two minutes of cold water at the end of a warm shower each morning
How cold is cold?
The benefits of cold exposure begin at around 16ºC / 60ºF, so in most places, water from the cold water mains is sufficiently cold.
As your body becomes more used to making the quick-change on a vascular level, the cold water will seem less shocking to your system. In other words, on day 30 it won’t hit you like it did on day one.
At that point, you can either continue with your two-minutes daily cold shower, and reap the benefits, or if you’re curious to push it further, that’s where ice baths come in!
Can anyone do it, or are any conditions contraindicated?
As ever, we’re a health and productivity newsletter, not doctors, let alone your doctors. Nothing here is medical advice. However, Wim Hof himself says:
❝Listen to your body, and never force the practices. We advise against doing Wim Hof Method if you are dealing with any of the following:
- Epilepsy
- High blood pressure
- Coronary heart disease
- A history of serious healthy issues like heart failure or stroke
- Pregnancy*
- Childhood*❞
*There is simply not enough science regarding the effects of cold exposure on people who are pregnant, or children. Obviously, we don’t expect this to be remedied anytime soon, because the study insitutions’ ethics boards would (rightly!) hold up the study.
As for the other conditions, and just generally if unsure, consult a doctor.
As you can see, this does mean that a limitation of Cold Therapy is that it appears to be far better as a preventative, since it helps guard against the very conditions that could otherwise become contraindications.
We haven’t peppered today’s main feature with study papers, partly because Wim Hof’s own website has kindly collated a collection of them (with links and summaries!) onto one page:
