Life is a marathon, not a sprint. For most of us, at least. But how do we pace ourselves to go the distance, without falling into complacency along the way?
According to our author Alex Hutchinson, there’s a lot more to it than goal-setting and strategy.
Hutchinson set out to write a running manual, and ended up writing a manual for life. To be clear, this is still mostly centered around the science of athletic endurance, but covers the psychological factors as much as the physical… and notes how the capacity to endure is the key trait that underlies great performance in every field.
The writing style is both personal and personable, and parts read like a memoir (Hutchinson himself being a runner and sports journalist), while others are scientific in nature.
As for the science, the kind of science examined runs the gamut from case studies to clinical studies. We examine not just the science of physical endurance, but the science of psychological endurance too. We learn about such things as:
- How perception of ease/difficulty plays its part
- What factors make a difference to pain tolerance
- How mental exhaustion affects physical performance
- What environmental factors increase or lessen our endurance
- …and many other elements that most people don’t consider
Bottom line: whether you want to run a marathon in under two hours, or just not quit after one minute forty seconds on the exercise bike, or to get through a full day’s activities while managing chronic pain, this book can help.

The Physical Exercises That Build Your Brain

Jim Kwik: from broken brain to brain coach
Image from Kwik Learning This is Jim Kwik. He suffered a traumatic brain injury as a small child, and later taught himself to read and write by reading comic books. He became fascinated with the process of learning, and in his late 20s he set up Kwik Learning, to teach accelerated learning in classrooms and companies, which he continued until 2009 when he launched his online learning platform. His courses have now been enjoyed by people in 195 countries.
So, since accelerated learning is his thing, you might wonder…
What does he have to share that we can benefit from in the next five minutes?
Three brain exercises to improve memory and concentration
A lot of problems we have with working memory are a case of executive dysfunction, but there are tricks we can use to get our brains into gear and make them cumulatively stronger:
First exercise
You can strengthen your corpus callosum (the little bridge between the two hemispheres of the brain) by performing a simple kinesiological exercise, such as alternating touching your left elbow to your right knee, and touching your right elbow to your left knee.
Do it for about a minute, but the goal here is not a cardio exercise, it’s accuracy!
You want to touch your elbow and opposite knee to each other as precisely as possible each time. Not missing slightly off to the side, not falling slightly short, not hitting it too hard.
Second exercise
Put your hands out in front of you, as though you’re about to type at a keyboard. Now, turn your hands palm-upwards. Now back to where they were. Now palm-upwards again. Got it? Good.
That’s not the exercise, the exercise is:
You’re now going to do the same thing, but do it twice as quickly with one hand than the other. So they’ll still be flipping to the same basic “beat”, put it in musical terms, the tempo on one hand will now be twice that of the other. When you get the hang of that, switch hands and do the other side.
This is again about the corpus callosum, but it’s now adding an extra level of challenge because of holding the two rhythms separately, which is also working the frontal lobe of the cerebral cortex.
The pre-frontal cortex in particular is incredibly important to executive function, self-discipline, and being able to “do” delayed gratification. So this exercise is really important!
Third exercise
This one works the same features of the brain, but most people find it harder. So, consider it a level-up on the previous:
Imagine there’s a bicycle wheel in front of you (as though the bike is facing you at chest-height). Turn the wheel towards you with your hands, one on each side.
Now, do the same thing, but each of your hands is going in the opposite direction. So one is turning the wheel towards you; the other is turning it away from you.
Now, do the same thing, but one hand goes twice as quickly as the other.
Switch sides.
Why is this harder for most people than the previous? Because the previous involved processing discrete (distinct from each other) movements while this one involves analog continuous movements.
It’s like reading an analog clock vs a digital clock, but while using both halves of your brain, your corpus callosum, your pre-frontal cortex, and the motor cortex too.

Cupping: How It Works (And How It Doesn’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.
Good Health By The Cup?
In Tuesday’s newsletter, we asked you for your opinion of cupping (the medical practice), and got the above-depicted, below-described, set of responses:
- About 40% said “It may help by improving circulation and stimulating the immune system”
- About 26% said “I have never heard of the medical practice of cupping before this”
- About 19% said “It is pseudoscience and/or placebo at best, but probably not harmful
- About 9% said “It is a good, evidence-based practice that removes toxins and stimulates health”
- About 6% said “It is a dangerous practice that often causes harm to people who need medical help”
So what does the science say?
First, a quick note for those unfamiliar with cupping: it is the practice of placing a warmed cup on the skin (open side of the cup against the skin). As the warm air inside cools, it reduces the interior air pressure, which means the cup is now (quite literally) a suction cup. This pulls the skin up into the cup a little. The end result is visually, and physiologically, the same process as what happens if someone places the nozzle of a vacuum cleaner against their skin. For that matter, there are alternative versions that simply use a pump-based suction system, instead of heated cups—but the heated cups are most traditional and seem to be most popular. See also:
National Center for Complementary and Integrative Health | Cupping
It is a dangerous practice that often causes harm to people who need medical help: True or False?
False, for any practical purposes.
- Directly, it can (and usually does) cause minor superficial harm, much like many medical treatments, wherein the benefits are considered to outweigh the harm, justifying the treatment. In the case of cupping, the minor harm is usually a little bruising, but there are other risks; see the link we gave just above.
- Indirectly, it could cause harm by emboldening a person to neglect a more impactful treatment for their ailment.
But, there’s nothing for cupping akin to the “the most common cause of death is when someone gets a vertebral artery fatally severed” of chiropractic, for example.
It is a good, evidence-based practice that removes toxins and stimulates health: True or False?
True and False in different parts. This one’s on us; we included four claims in one short line. But let’s look at them individually:
- Is it good? Well, those who like it, like it. It legitimately has some mild health benefits, and its potential for harm is quite small. We’d call this a modest good, but good nonetheless.
- Is it evidence-based? Somewhat, albeit weakly; there are some papers supporting its modest health claims, although the research is mostly only published in journals of alternative medicine, and any we found were in journals that have been described by scientists as pseudoscientific.
- Does it remove toxins? Not directly, at least. There is also a version that involves making a small hole in the skin before applying the cup, the better to draw out the toxins (called “wet cupping”). This might seem a little medieval, but this is because it is from early medieval times (wet cupping’s first recorded use being in the early 7th century). However, the body’s response to being poked, pierced, sucked, etc is to produce antibodies, and they will do their best to remove toxins. So, indirectly, there’s an argument.
- Does it stimulate health? Yes! We’ll come to that shortly. But first…
It is pseudoscience and/or placebo at best, but probably not harmful: True or False?
True in that its traditionally-proposed mechanism of action is a pseudoscience and placebo almost certainly plays a strong part, and also in that it’s generally not harmful.
On it being a pseudoscience: we’ve talked about this before, but it bears repeating; just because something’s proposed mechanism of action is pseudoscience, doesn’t necessarily mean it doesn’t work by some other mechanism of action. If you tell a small child that “eating the rainbow” will improve their health, and they believe this is some sort of magical rainbow power imbuing them with health, then the mechanism of action that they believe in is a pseudoscience, but eating a variety of colorful fruit and vegetables will still be healthy.
In the case of cupping, its proposed mechanism of action has to do withbalancing qi, yin and yang, etc (for which scientific evidence does not exist), in combination with acupuncture lore (for which some limited weak scientific evidence exists). On balancing qi, yin and yang etc, this is a lot like Europe’s historically popular humorism, which was based on the idea of balancing the four humors (blood, yellow bile, black bile, phlegm). Needless to say, humorism was not only a pseudoscience, but also eventually actively disproved with the advent of germ theory and modern medicine. Cupping therapy is not more scientifically based than humorism.
On the placebo side of things, there probably is a little more to it than that; much like with acupuncture, a lot of it may be a combination of placebo and using counter-irritation, a nerve-tricking method to use pain to reduce pain (much like pressing with one’s nail next to an insect bite).
Here’s one of the few studies we found that’s in what looks, at a glance, to be a reputable journal:
Cupping therapy and chronic back pain: systematic review and meta-analysis
It may help by improving circulation and stimulating the immune system: True or False?
True! It will improve local circulation by forcing blood into the area, and stimulate the immune system by giving it a perceived threat to fight.
Again, this can be achieved by many other means; acupuncture (or just “dry needling”, which is similar but without the traditional lore), a cold shower, and/or exercise (and for that matter, sex—which combines exercise, physiological arousal, and usually also foreign bodies to respond to) are all options that can improve circulation and stimulate the immune system.

From Painkillers To Hunger-Killers
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.
Here’s this week’s selection of health news discoveries, the science behind them, what they mean for you, and where you can go from there:
Killing more than pain
It’s well-known that overuse of opioids can lead to many problems, and here’s another one: messing with the endocrine system. This time, mostly well-evidenced in men—however, the researchers are keen to point out that absence of evidence is very much not evidence of absence, hence “the hidden effects” in the headline below. It’s not that the effects are hard to see—it’s that a lot of the research has yet to be done. For now, though, we know at the very least that there’s an association between opioid use and hyperprolactinemia in men. The same research also begins to shine a light on the effects of opioid use on the hypothalamic-pituitary system and bone health, too:

Gut microbiome dysbiosis may lead to slipping disks
These things sound quite unconnected, but the association is strong. The likely mechanism of action is that the gut dysbiosis influences systemic inflammation, and thus spinal health—because the gut-spine axis cannot really be disconnected (while you’re alive, at least). It’s especially likely if you’re over 50 and female:

The Internet is really really great (for brains)
It’s common to see many articles on the Internet telling us, paradoxically, that we should spend less time on the Internet. However… Remember when in the 90s, it was all about “the information superhighway”? It turns out, the fact that it’s more like “the information spaghetti junction” these days doesn’t change the fact that stimulation is good for our brains, and daily Internet use improves memory, because of the different way that we index and store information that came from a virtual source. While there are parts of your brain for “things at home” and “things at the local supermarket”, there are also parts for “things at 10almonds” and “things at Facebook” and so forth. You are, in effect, building a vast mental library as you surf:

Fall back
Around this time of year in many places in the Northern Hemisphere, the clocks go back an hour (it’s next weekend in the US and Canada, by the way, and this weekend in most of Europe). Many enjoy this as the potential for an extra hour’s sleep, but for night owls, it can be more of a nuisance than a benefit—throwing out what’s often an already difficult relationship with the clock, and presenting challenges both practical and physiological (different processing of melatonin, for instance). Here be science:

Can you outrun your hunger?
It seems so, though benefits are strongest in women. We say “outrun”, though this study did use stationary cycling. To put it in few words, intense exercise (but not moderate exercise) significantly reduced acylated ghrelin (hunger hormone) levels, and subjective reports of hunger, especially in women:

Pumpkin Seeds vs Watermelon Seeds – 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 pumpkin seeds to watermelon seeds, we picked the watermelon.
Why?
Starting with the macros: pumpkin seeds have a lot more carbs, while watermelon seeds have a lot more protein, despite pumpkin seeds being famous for such. They’re about equal on fiber. In terms of fats, watermelon seeds are higher in fats, and yes, these are healthy fats, mostly polyunsaturated.
When it comes to vitamins, pumpkin seeds are marginally higher in vitamins A and C, while watermelon seeds are a lot higher in vitamins B1, B2, B3, B5, B6, and B9. An easy win for watermelon seeds here.
In the category of minerals, despite being famous for zinc, pumpkin seeds are higher only in potassium, while watermelon seeds are higher in iron, magnesium, manganese, and phosphorus; the two seeds are equal on calcium, copper, and zinc. Another win for watermelon seeds.
In short, enjoy both, but watermelon has more to offer. Of course, if buying just the seeds and not the whole fruit, it’s generally easier to find pumpkin seeds than watermelon seeds, so do bear in mind that pumpkin seeds’ second place isn’t that bad here—it’s just a case of a very nutritious food looking bad by standing next to an even better one.

Digital Minimalism – by Dr. Cal Newport
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.
There are a lot of books that advise “Unplug once in a while, and go outside”. But it doesn’t really take a book to convey that, does it? And it just leaves all the digital catching-up once we get back. Surely there must be a better way?
Rather than relying on a “digital detox”, Dr. Newport offers principles to apply to our digital lives, that allow us to reap the benefits of modern information technology without being obeisant to it.
The book’s greatest strength lies in that; having clear guidelines that can be applied to cut out the extra weight of digital media that has simply snuck in because of The Almighty Algorithm—and even tips on how to engage more mindfully with that if we still want to, for example using social media only in a web browser rather than on our phones, so that we can ringfence the time for it rather than having it spill into every spare moment.
In the category of criticism, the book sometimes lacks a little awareness when it comes to assumptions about the reader and the reader’s social circles; that (for example) nobody has any disabilities and everyone lives in the same town. But for most people most of the time, the advices will stand, and the exceptions can be managed by the reader neatly enough.
Stylistically, the book is not very minimalist, but this is not inconsistent with the advice of the book, if you’re curling up in the armchair with a physical copy, or a single-purpose ereader device.
Bottom line: if you’d like to streamline your use of digital media, but don’t want to lose out on the value it brings you, this book provides an excellent template
