10almonds tip: take a breath, and take a moment to notice that you’re looking out from behind your eyes. Mindfulness doesn’t have to be reserved for mountaintop retreats! It can—and must—exist in the little moments too.

In today’s email we cover caffeine & exercise in the heat, isolation & the brain, and life & death & life again.

Not feeling as strong as you used to? It’s not just about muscle mass, but also about mitochondrial function, without which your muscles can’t do much. Today’s sponsor, Timeline, is offering a mitochondria-boosting supplement that we wrote about previously as part of Dr. Greger’s Anti-Aging Eight, which is a list of incredibly well-evidenced longevity-inducing things we can take (if you’re looking for it in the list, it’s urolithin A, which you can see in our sponsor’s store, here) ← 30% off for 10almonds readers with code 30NEWSLETTER, by the way!

Humans are, by evolution, social creatures. As individuals we may have something of a spectrum from introvert to extrovert, but as a species, we thrive in community. And we suffer, when we don’t have that.

But how?

As our muscles age, they naturally lose mass, strength, and function—a result of certain muscle fibers shrinking—contributing to fatigue and weakness beginning as early as our 30s.

Recent research highlights that the key player in this aging process is our mitochondria, tiny-but-mighty organelles that produce more than 90% of our body’s energy. Importantly, scientists have found a strong link between decreased mitochondrial health and muscle health decline with aging, emphasizing the importance of maintaining these cellular engines.

A new way to support and improve muscle health as we age, Mitopure® by Timeline is clinically shown to meaningfully boost our mitochondrial health to improve muscle strength and endurance, without any change in exercise required.

Ready to feel stronger, for longer with Mitopure?

Yesterday we asked you to choose between mango and peach—we picked the mango (click here to read about why), as did 62% of you!

Now for today’s choice:

The main content of this book is stories (true ones, but it would do them a disservice to call them anecdotes, and it would be unduly clinical to call them case studies) of people who by a certain definition died—in the sense that their hearts stopped—but timely medical intervention allowed them to “come back to life” and continue living. Each gets a chapter devoted to them.

Others weren’t so lucky; some of the chapters also remember those who didn’t come back. For example: two teenagers struck by the same bolt of lightning; a passerby rushed to give CPR to the one he saw first, only afterwards seeing the other. Fate can be like that.

While the randomness of life and death can be utterly dispassionate, those of us who live on are often not nearly so unfeeling, and this book is about that. Making sense of the senseless, finding meaning, and truly appreciating life in all its heights and depths.

The style is very personal, and most of it comes in the form of retrospective narrative prose, with present-day quotations (the author, an ICU doctor who encounters many such cases, interviewed the survivors for this book, whence the stories) that really drive home the lasting impacts of the experiences (many of the interviews are years, sometimes decades, after the event), and the remarkable diversity of emotional responses on a person-by-person basis.

Bottom line: this book is very engaging from start to finish, and is very thought-provoking. If you’re anything like this reviewer, you might take little crying breaks from time to time, but it’s all very much worth it.
