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.”

What is ‘breathwork’? And do I need to do it?
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.
From “breathwork recipes” to breathing techniques, many social media and health websites are recommending breathwork to reduce stress.
But breathwork is not new. Rather it is the latest in a long history of breathing techniques such as Pranayama from India and qigong from China. Such practices have been used for thousands of years to promote a healthy mind and body.
The benefits can be immediate and obvious. Try taking a deep breath in through your nose and exhaling slowly. Do you feel a little calmer?
So, what’s the difference between the breathing we do to keep us alive and breathwork?
Taras Grebinets/Shutterstock Breathwork is about control
Breathwork is not the same as other mindfulness practices. While the latter focus on observing the breath, breathwork is about controlling inhalation and exhalation.
Normally, breathing happens automatically via messages from the brain, outside our conscious control. But we can control our breath, by directing the movement of our diaphragm and mouth.
The diaphragm is a large muscle that separates our thoracic (chest) and abdominal (belly) cavities. When the diaphragm contracts, it expands the thoracic cavity and pulls air into the lungs.
Controlling how deep, how often, how fast and through what (nose or mouth) we inhale is the crux of breathwork, from fire breathing to the humming bee breath.
Breathwork can calm or excite
Even small bits of breathwork can have physical and mental health benefits and complete the stress cycle to avoid burnout.
Calming breathwork includes diaphragmatic (belly) breathing, slow breathing, pausing between breaths, and specifically slowing down the exhale.
In diaphragmatic breathing, you consciously contract your diaphragm down into your abdomen to inhale. This pushes your belly outwards and makes your breathing deeper and slower.
You can also slow the breath by doing:
- box breathing (count to four for each of four steps: breathe in, hold, breathe out, hold), or
- coherent breathing (controlled slow breathing of five or six breaths per minute), or
- alternate nostril breathing (close the left nostril and breathe in slowly through the right nostril, then close the right nostril and breathe out slowly through the left nostril, then repeat the opposite way).
You can slow down the exhalation specifically by counting, humming or pursing your lips as you breathe out.
In contrast to these calming breathing practices, energising fast-paced breathwork increases arousal. For example, fire breathing (breathe in and out quickly, but not deeply, through your nose in a consistent rhythm) and Lion’s breath (breathe out through your mouth, stick your tongue out and make a strong “haa” sound).
What is happening in the body?
Deep and slow breathing, especially with a long exhale, is the best way to stimulate the vagus nerves. The vagus nerves pass through the diaphragm and are the main nerves of the parasympathetic nervous system.
Simulating the vagus nerves calms our sympathetic nervous system (fight or flight) stress response. This improves mood, lowers the stress hormone cortisol and helps to regulate emotions and responses. It also promotes more coordinated brain activity, improves immune function and reduces inflammation.
Taking deep, diaphragmatic breaths also has physical benefits. This improves blood flow, lung function and exercise performance, increases oxygen in the body, and strengthens the diaphragm.
Slow breathing reduces heart rate and blood pressure and increases heart rate variability (normal variation in time between heart beats). These are linked to better heart health.
Taking shallow, quick, rhythmic breaths in and out through your nose stimulates the sympathetic nervous system. Short-term, controlled activation of the stress response is healthy and develops resilience to stress.
Breathing in through the nose
We are designed to inhale through our nose, not our mouth. Inside our nose are lots of blood vessels, mucous glands and tiny hairs called cilia. These warm and humidify the air we breathe and filter out germs and toxins.
We want the air that reaches our airways and lungs to be clean and moist. Cold and dry air is irritating to our nose and throat, and we don’t want germs to get into the body.
Nasal breathing increases parasympathetic activity and releases nitric oxide, which improves airway dilation and lowers blood pressure.
Consistently breathing through our mouth is not healthy. It can lead to pollutants and infections reaching the lungs, snoring, sleep apnoea, and dental issues including cavities and jaw joint problems.
Breathing can be high and shallow when we are stressed. mi_viri/Shutterstock A free workout
Slow breathing – even short sessions at home – can reduce stress, anxiety and depression in the general population and among those with clinical depression or anxiety. Research on breathwork in helping post-traumatic stress disorder (PTSD) is also promising.
Diaphragmatic breathing to improve lung function and strengthen the diaphragm can improve breathing and exercise intolerance in chronic heart failure, chronic obstructive pulmonary disease and asthma. It can also improve exercise performance and reduce oxidative stress (an imbalance of more free radicals and/or less antioxidants, which can damage cells) after exercise.
Waiting at the lights? This could be your signal to do some breathwork. doublelee/Shutterstock A mind-body connection you can access any time
If you feel stressed or anxious, you might subconsciously take shallow, quick breaths, but this can make you feel more anxious. Deep diaphragmatic breaths through your nose and focusing on strong exhalations can help break this cycle and bring calm and mental clarity.
Just a few minutes a day of breathwork can improve your physical and mental health and wellbeing. Daily deep breathing exercises in the workplace reduce blood pressure and stress, which is important since burnout rates are high.
Bottom line: any conscious control of your breath throughout the day is positive.
So, next time you are waiting in a line, at traffic lights or for the kettle to boil, take a moment to focus on your breath. Breathe deeply into your belly through your nose, exhale slowly, and enjoy the benefits.

Ice Baths: To Dip Or Not To Dip?
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 Are Cold, But Few Are Frozen
We asked you for your (health-related) view of ice baths, and got the above-depicted, below-described, set of responses:
- About 31% said “ice baths are great for the health; we should take them”
- About 29% said “ice baths’ risks outweigh their few benefits”
- About 26% said “ice baths’ benefits outweigh their few risks”
- About 14% said “ice baths are dangerous and can kill you; best avoided”
So what does the science say?
Freezing water is very dangerous: True or False?
True! Water close to freezing point is indeed very dangerous, and can most certainly kill you.
Fun fact, though: many such people are still saveable with timely medical intervention, in part because the same hypothermia that is killing them also slows down the process* of death
Source (and science) for both parts of that:
Cold water immersion: sudden death and prolonged survival
*and biologically speaking, death is a process, not an event, by the way. But we don’t have room for that today!
(unless you die in some sudden violent way, such as a powerful explosion that destroys your brain instantly; then it’s an event)
Ice baths are thus also very dangerous: True or False?
False! Assuming that they are undertaken responsibly and you have no chronic diseases that make it more dangerous for you.
What does “undertaken responsibly” mean?
Firstly, the temperature should not be near freezing. It should be 10–15℃, which for Americans is 50–59℉.
You can get a bath thermometer to check this, by the way. Here’s an example product on Amazon.
Secondly, your ice bath should last no more than 10–15 minutes. This is not a place to go to sleep.
What chronic diseases would make it dangerous?
Do check with your doctor if you have any doubts, as no list we make can be exhaustive and we don’t know your personal medical history, but the main culprits are:
- Cardiovascular disease
- Hypertension
- Diabetes (any type)
The first two are for heart attack risk; the latter is because diabetes can affect core temperature regulation.
Ice baths are good for the heart: True or False?
True or False depending on how they’re done, and your health before starting.
For most people, undertaking ice baths responsibly, repeated ice bath use causes the cardiovascular system to adapt to better maintain homeostasis when subjected to thermal shock (i.e. sudden rapid changes in temperature).
For example: Respiratory and cardiovascular responses to cold stress following repeated cold water immersion
And because that was a small study, here’s a big research review with a lot of data; just scroll to where it has the heading“Specific thermoregulative adaptations to regular exposure to cold air and/or cold water exposure“ for many examples and much discussion:
Health effects of voluntary exposure to cold water: a continuing subject of debate
Ice baths are good against inflammation: True or False?
True! Here’s one example:
Uric acid and glutathione levels (important markers of chronic inflammation) are also significantly affected:
Uric acid and glutathione levels during short-term whole body cold exposure

The Good Skin Solution – by Shann Jones
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.
Not everyone knows that eczema is not just a skin condition; it’s an autoimmune condition. And thus to heal one’s skin, the gut is a good place to start.
This is not your average gut health book though, because it is focused on optimizing things for one’s skin… Although the author herself learned about this while helping her husband to battle an MRSA infection. In other words, a multi-fronted battle for sure.
The advices in this book are good for, as the subtitle promises, an assortment of other skin conditions too, including psoriasis, rosacea, and acne. She covers the usual bases, and recommends probiotics, of which she’s particularly keen to praise kefir, while advising against the use of antibiotics unless absolutely necessary—something we’ve talked about from time to time at 10almonds, too.
Not content to merely cover those things, she also talks allergies, and walking the fine line between avoiding triggers and developing hypersensitivity by treating to live in a perfectly clean bubble.
Ultimately, she offers “7 daily habits”, 3 of which involve goat’s milk kefir, that’s how keen on it she is. So if you’re vegan, probably this book isn’t as good value, however much it discusses the health woes that can be caused and/or exacerbated by drinking cow’s milk.
The style is very light and personable, which makes for easy reading, more like one friend talking to another, than a scientific textbook.
Bottom line: if you’d like healthier skin, are interested in dietary tweaks and homemade soaps, and have no aversion to goat’s milk and/or kefir, then this book is full of fascinating pointers.

Taurine’s Benefits For Heart Health And More
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.
Taurine: Research Review
First, what is taurine, beyond being an ingredient in many energy drinks?
It’s an amino acid that many animals, including humans, can synthesize in our bodies. Some other animals—including obligate carnivores such as cats (but not dogs, who are omnivorous by nature) cannot synthesize taurine and must get it from food.
So, as humans are very versatile omnivorous frugivores by nature, we have choices:
- Synthesize it—no need for any conscious action; it’ll just happen
- Eat it—by eating meat, which contains taurine
- Supplement it—by taking supplements, including energy drinks, which generally (but not always) use a bioidentical lab-made taurine. Basically, lab-made taurine is chemically identical to the kind found in meat, it’s just cheaper and doesn’t involve animals as a middleman.
What does it do?
Taurine does a bunch of essential things, including:
- Maintaining hydration/electrolyte balance in cells
- Regulating calcium/magnesium balance in cells
- Forming bile salts, which are needed for digestion
- Supporting the integrity of the central nervous system
- Regulating the immune system and antioxidative processes
Thus, a shortage of taurine can lead to such issues as kidney problems, eye tissue damage (since the eyes are a particularly delicate part of the CNS), and cardiomyopathy.
If you want to read more, here’s an academic literature review:
Taurine: A “very essential” amino acid
On the topic of eye health, a 2014 study found that taurine is the most plentiful amino acid in the eye, and helps protect against retinal degeneration, in which they say:
❝We here review the evidence for a role of taurine in retinal ganglion cell survival and studies suggesting that this compound may be involved in the pathophysiology of glaucoma or diabetic retinopathy. Along with other antioxidant molecules, taurine should therefore be seriously reconsidered as a potential treatment for such retinal diseases❞

Taurine for muscles… In more than sports!
We’d be remiss not to mention that taurine is enjoyed by athletes to enhance athletic performance; indeed, it’s one of its main selling-points:
See: Taurine in sports and exercise
But! It’s also useful for simply maintaining skeleto-muscular health in general, and especially in the context of age-related decline and chronic disease:
Taurine: the appeal of a safe amino acid for skeletal muscle disorders
On the topic of safety… How safe is it?
There’s an interesting answer to that question. Within safe dose ranges (we’ll get to that), taurine is not only relatively safe, but also, studies that looked to explore its risks found new benefits in the process. Specifically of interest to us were that it appears to promote better long-term memory, especially as we get older (as taurine levels in the brain decline with age):
Taurine, Caffeine, and Energy Drinks: Reviewing the Risks to the Adolescent Brain
^Notwithstanding the title, we assure you, the research got there; they said:
❝Interestingly, the levels of taurine in the brain decreased significantly with age, which led to numerous studies investigating the potential neuroprotective effects of supplemental taurine in several different experimental models❞
What experimental models were those? These ones:
- Taurine protects cerebellar neurons of the external granular layer
- Effects of taurine on alterations of neurobehavior and neurodevelopment key proteins expression
- Neuroprotective role of taurine in developing offspring affected by maternal alcohol consumption
…which were all animal studies, however.
The same systematic review also noted that not only was more research needed on humans, but also, existing studies have had a strong bias to male physiology (in both human and assorted other animal studies), so more diverse study is needed too.
What are the safe dose ranges?
Before we get to toxicity, let’s look at some therapeutic doses. In particular, some studies that found that 500mg 3x daily, i.e. 1.5g total daily, had benefits for heart health:
- Taurine and atherosclerosis
- The Anti-Inflammatory Effect of Taurine on Cardiovascular Disease
- Taurine supplementation has anti-atherogenic and anti-inflammatory effects before and after incremental exercise in heart failure
- Taurine Supplementation Lowers Blood Pressure and Improves Vascular Function in Prehypertension
- Taurine improves the vascular tone through the inhibition of TRPC3 function in the vasculature
Bottom line on safety: 3g/day has been found to be safe:

Black Beans vs Pinto Beans – 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 black beans to pinto beans, we picked the pinto beans.
Why?
Both of these beans have won all their previous comparisons, so it’s no surprise that this one was very close. Despite their different appearance, taste, and texture, their nutritional profiles are almost identical:
In terms of macros, pinto beans have a tiny bit more protein, carbs, and fiber. So, a nominal win for pinto beans, but again, the difference is very slight.
When it comes to vitamins, black beans have more of vitamins A, B1, B3, and B5, while pinto beans have more of vitamins B2, B6, B9, C, E, K and choline. Superficially, again this is nominally a win for pinto beans, but in most cases the differences are so slight as to be potentially the product of decimal place rounding.
In the category of minerals, black beans have more calcium, copper, iron, and phosphorus, while pinto beans have more magnesium, manganese, selenium, and zinc. That’s a 4:4 tie, but the only one with a meaningful margin of difference is selenium (of which pinto beans have 4x more), so we’re calling this one a very modest win for pinto beans.
All in all, adding these up makes for a “if we really are pressed to choose” win for pinto beans, but honestly, enjoy either in accordance with your preference (this writer prefers black beans!), or better yet, both.

Ultra-Processed People – by Dr. Chris van Tulleken
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.
It probably won’t come as a great surprise to any of our readers that ultra-processed food is—to make a sweeping generalization—not fabulous for the health. So, what does this book offer beyond that?
Perhaps this book’s greatest strength is in showing not just what ultra-processed foods are, but why they are. In principle, food being highly processed should be neither good nor bad by default. Much like GMOs, if a food is modified to be more nutritious, that should be good, right?
Only, that’s mostly not what happens. What happens instead is that food is modified (be it genetically or by ultra-processing) to be cheaper to produce, and thus maximise the profit margin.
The addition of a compound that increases shelf-life but harms the health, increases sales and is a net positive for the manufacturer, for instance. Dr. van Tulleken offers us many, many, examples and explanations of such cost-cutting strategies at our expense.
In terms of qualifications, the author has an MD from Oxford, and also a PhD, but the latter is in molecular virology; not so relevant here. Yet, we are not expected to take an “argument from authority”, and instead, Dr. van Tulleken takes great pains to go through a lot of studies with us—the good, the bad, and the misleading.
If the book has a downside, then this reviewer would say it’s in the format; it’s less a reference book, and more a 384-page polemic. But, that’s a subjective criticism, and for those who like that sort of thing, that is the sort of thing that they like.
