[Note: This book is about sport and exercise science, particularly as they pertain to the martial arts. If you’re a martial artist or are interested in fitness and movement arts at the extremes of human capacity, you’re in the right place. If you’re interested in the comics and an overview of topics including how many billions Bruce Wayne needs and what technologies Batman must master, those aren’t questions addressed in this book. Such readers may find the book delving into depths they aren’t interested in on biological science. There are articles on the web that deal with topics like the “Cost of being Batman.”]

Next summer an eagerly awaited movie entitled Batman v Superman: Dawn of Justice hits theaters. Who knows how much screen time will involve the fight between the titular characters, but the same battle has played out a number of times in the comics, and its appeal is clear. What are the limits of human capability given training, technology, and sufficient smarts? Can a man really defeat an alien that’s faster than a bullet and more powerful than a locomotive? A popular fanboy mantra is, “I like Batman, because I could be Batman. Batman has no superpowers.” So, yes, if you were a billionaire, genius, with the physique of a Greek god, and knew 127 martial arts, you too could be Batman. Or could you? That question is at the heart of Zehr’s book.

Becoming Batman is arranged into sixteen chapters divided among five parts. It begins logically with the question of whether Bruce Wayne needs to begin at any particular point to achieve success in transforming himself into Batman? (At the extreme, one probably can’t imagine Bruce Wayne becoming Batman if he was born with one leg a foot longer than the other and with a Quasimodo hump, but given a Bruce who is starting out “average,” what are his limitations.) In other words, how much does genetics come into play. In the first part, Zehr introduces a character, Bob Wayne, who doesn’t appear in the comics. Bob is Bruce’s twin, and is used throughout the book for comparison purposes, i.e. to convey what Bruce Wayne would look like if he didn’t train fanatically to be Batman. The question of how much of Batman is innate and how much is painstaking built by exercise and training is critical to determining how many of those fanboys really could be Batman.

There a series of chapters explaining the mechanism by which stressors result in a stronger, faster, more powerful, and more resilient Batman. The idea is that Mother Nature doesn’t over-engineer. The only way one gets stronger muscles is by overloading them, which triggers a process of rebuilding them bigger and better than before. Wolff’s Law defines the same concept for bones, i.e. bone density increases in response to increased loading. (Incidentally, the same is true of the mind. A more agile mind is achieved only by working it, and zoning out in front of the television results in a dumbening.)

The next section shifts from generic exercise science to questions of Batman’s martial arts training. What kind of martial arts (or arts) would Batman practice? There is an often quoted statement in the comics to the effect that Batman had mastered 127 martial arts. (This is ridiculous, but it does spur the intriguing question of how many systems does Batman need to learn to have a well-rounded skill-base without being a dabbler? Many will say one art—the right one–is enough, others will say that–given the varied cast of villains he must defeat–Batman needs a broader skill-set than any existing art provides.) More to the point, how many hours does one need to practice a technique to ingrain the movements into one (e.g. neurologically it takes repetition to optimize efficiency.) This is among the questions discussed in this book.

The fourth section deals with the ravages of being Batman, and how much any human could be expected to endure. In this section, one will learn about the cumulative toll of concussions, the likelihood of Batman avoiding broken bones and other injuries that would necessarily sideline his crime fighting, and the effect that working the night shift would have. (The latter might seem trivial in comparison to the former two topics, but—in fact—it’s not. It’s well established that night workers have higher incidence of some cancers and other ailments. Furthermore, as Bruce Wayne has to keep appearances up, it means not only fighting circadian rhythm issues, but also frequent sleep deprivation—the hazards of which are even clearer and occur in short order.)

There are a number of interesting topic that aren’t don’t pertain to the core question per se, but which are interesting for fans of the Batman canon and the character’s mythos. Famously, Batman doesn’t use guns or lethal force. This raises the question of how realistic it is to regularly fight hardened knaves and miscreants without killing them. One can only knock out so many of Gotham’s baddies before one doesn’t get up.

There’s a chapter about what a fight between Batman and Batgirl would be like. While strength would definitely be to Batman’s advantage, there are advantages that an equally skilled female fighter might bring to the fight? How would Batgirl (or Catwoman) need to fight to put those advantages to use? Finally, for those of us who are no longer spring chicks, there are chapters about how Batman could expect to age, and how long he could keep performing at a level at which he could defeat his enemies.

I enjoyed this book and found it both educational and interesting. It should be clear that Batman is just a teaching tool used to explore the limitations of the human body and its ability to endure a life of fighting. That said, references to the Batman comic books and movies makes for a readable text. Perhaps what I like most about this book is that most of the books that address these subjects are textbooks that are sold on the textbook pricing model (i.e. we have a limited but captive audience so let’s make them pay top dollar.) This is one of the few books that takes on these topics at the readability and pricing model of a popular science book.

I recommend it for those interested in the science of performance, martial arts, and injury.

The Key Muscles of Hatha YogaThe Key Muscles of Hatha Yoga by Ray Long

My rating: 4 of 5 stars

Amazon page

This is a handy anatomy reference for yoga teachers and practitioners. The bulk of the book describes major muscles, or—when relevant—muscle groups. For each of the key muscles it gives the insertion, origin, innervation, agonists, synergists, and depicts the muscle in color drawings. The book also shows typical yoga postures in which the muscle is engaged or stretched. This gives one some idea of how the muscle is affected by changes in attitude and state of contraction.

True to the title, this isn’t a general anatomy and physiology book for yoga. It specifically deals with the muscular system. That being said, it does have some opening matter on the skeletal system, the various types of joints, and other fundamentals that one must understand to grasp how muscles create movement and change bodily alignment. It also has a few brief chapters at the end that deal with important issues like breathing and bandhas. However, if you’re looking for a book with substantial coverage of the anatomy and physiology of breath or nervous system activity, you’ll likely need to look elsewhere. The book also addresses the concept of chakra, which seems out-of-place in an otherwise scientific book, but it will be appreciated by those who view the body in that way and is easily enough ignored for those who want a strictly scientific presentation of material.

While the book is limited in its focus, it does a good job of giving a lot of information in a concise fashion. The graphics are easily interpreted and one can readily distinguish the muscles in question. I found the book to be well-organized and easy to use.

I’d recommend this book for any serious yoga practitioners, particularly teachers and those who need to be concerned about the minutiae of movement and alignment.

BOOK REVIEW: The Wild Life of Our Bodies by Rob Dunn

The Wild Life of Our Bodies: Predators, Parasites, and Partners That Shape Who We Are TodayThe Wild Life of Our Bodies: Predators, Parasites, and Partners That Shape Who We Are Today by Rob Dunn

My rating: 4 of 5 stars

Amazon page

Dunn’s book addresses a host of intriguing questions such as:

-Why are there diseases that disproportionately attack those in the richest parts of the world while being almost non-existent in poor countries?
-Why is obesity at epidemic proportions among modern humans?
-Why—while people have diverse tastes overall—do there seem to be universal preferences for sweet, salty, and fatty foods?
-Why are so many people’s lives wrecked by constant stress and worry?
-Is the Appendix really a vestigial organ with no apparent purpose?

As the subtitle suggests, this book is about the role that other species have played in human evolution and the way we look, behave, and think today. The message of The Wild Life of Our Bodies is that humanity’s proclivity to see itself as an island–uninfluenced by other species–has its cost.

The book is popular science–approachable to a layman but with the usual disdain for gratuitous assertions and shoddy reasoning that define the scientific though process. That being said, Dunn does put some editorial opinion out there in ways that might appear as fact in a slipshod reading. The most prominent example being Dunn’s suggesting that what best defines humanity is not our intelligence or ability for abstract representation (or even our physical appearance), but that we are the only (first?) species that has killed other species off not purely of self-defense or for food, but to exercise control over our ecosystem. I doubt this would strike a majority of impartial scientists as a fair and unbiased way to define humanity. Granted, this point not what The Wild Life of Our Bodies is about, and whether one thinks this it is fair or not is not critical to whether one will find the book to be of value. However, the idea (and the fact) that humans have zealously killed off other creatures is certainly relevant to the discussion at hand.

If “terraforming” is the term for how an alien race might environmentally engineer Earth to make it suitable for them to live here, perhaps we could call humanity’s assault on other species “bio-forming” of the planet—choosing a roster of species that strikes our fancy. All the time humans were trying to make ourselves more comfortable by getting rid of inconvenient species, we remained ignorant to the downside.

Dunn covers a broad range of mismatches between who we are evolutionarily and how we live in the modern world. The Wild Life of Our Bodies suggests that, like the pronghorn antelope, humans are in many cases over-designed because of the loss of species (parasites, predators, symbiotes, etc.) that helped to make us who we are today. (One question that once puzzled biologists was why pronghorns were so much faster than every species they faced.)

While it sounds good to be over-designed (at least relative to the alternative), it’s not without cost. In our case, we had guts that were supremely adapted to having parasites, but the lightning fast (on an evolutionary timescale) elimination of those parasites has left us with bodies that attack a non-existent enemy and this has resulted in a number of new diseases. We are used to diseases that succeed in the poorest—and, hence, least hygienic areas– but disease that mostly attacked in the cleanest places on Earth have puzzled us for some time. Crohn’s disease is a prime example. “Rewilding” (i.e. putting parasites back into) the guts of Crohn’s patients has shown positive results.

Dunn lays out a couple of the theories as to how the loss of our intestinal bacteria may result in a number of first-world ailments. Interestingly, some of these diseases aren’t even digestive in nature, and might seem to have no logical connection to gut bacteria. However, our body’s systems are a system-of-systems—i.e. they are integrally linked. One issue is that some parasites have been able to mask their presence, and our bodies have learned to present a heightened response to account for this veiled threat. Today our systems can’t tell the difference between our squeaky clean guts and a gut full of these sneaking parasites so it drops the immune system version of an A-bomb.

This is one example of why some diseases don’t exist in the third-world where the body knows what parasites it’s up against. One might say, “Yes, but these ailments of over-reactive systems can’t be as bad as the effects of the parasites.” That’s often not true. Most people with internal bugs (we all have them to some degree), don’t even realize it. The fact that people with Crohns’ are willing to have predators implanted in them speaks to this issue.

There has been concern for years about downside of the rampant use of anti-bacterials, antibiotics, and antiseptics, and this is a topic Dunn addresses as well. For example, there seems to be little evidence that such agents in soap do any particular good, but they decidedly do bad (encouraging drug resistant species.)

Perhaps the single greatest change in the nature of homo sapiens life resulted from the agricultural revolution, and Dunn delves into how this seminal event changed our bodies. With paleo-dieting all the rage, it will come as no surprise that there have been some major changes to the human diet since our hunter-gatherer ancestors roamed the Earth. Once again, we have bodies built on an evolutionary timescale, and they don’t necessarily cope well with our new diets.

One problem is that we have strong hardwired drives for foods that were a rarity in our species’ past, but which we now produce in abundance. For example, we eat far too much refined sugar because our bodies are wired to love sweet, but that kind of food was rare to our pre-agricultural ancestors. Hence we have the existence of diabetes, and its greater prevalence where high-sugar diets are common. Many people are also saddled with an evolutionary advantage to store fat because their ancestors come from a clime where food was not abundant year round. The problem is that now there’s a grocery store on every corner and this once great advantage is contributing to burgeoning waistlines.

I gave this book a high rating on the grounds that it presented a lot of food for thought, and that’s what I most value in non-fiction. Some of the theories may turn out to be incorrect, but this book offers one a lot to think about and clear explanations of the bases for what can otherwise seem a little outlandish. There is also some wit in places that contributes to heightened readability.
