Like other reviewers, I was left disappointed because this book was not what I expected it to be. Maybe it was our fault for not reading the blurb too closely, but I do think the subtitle “Cannibals, Killer Viruses, and Other Journeys to the Edge of Science” is very misleading.
Of all the chapters in this book, the “cannibal” chapter was by far the most interesting to me, and of course, the most attention grabbing - but after learning what this refers to, I feel like “cannibal” is a very unfair word to use. The topic is Lesch-Nyhan Syndrome, a genetic disease that affects many aspect of a sufferer’s life. A prominent characteristic is self-harming and self-sabotaging behavior, including (but not limited to) biting off the lips and fingers - against their own will.
They are not compelled to “eat” themselves, rather they often ask to be restrained and yell for help when they feel the compulsion to hurt themselves. This behavior also displays socially, where they may reject gifts they actually want, fail on purpose when they want to succeed, and provoking anger when they want affection. I quickly understood that this trait was mental far more than it was physical, although it often manifests physically in self-harm.
For some it may be extreme nail-biting, which I would hardly classify as cannibalism. Although some patients have permanently mutilated themselves, it is not “cannibalism” just because they may have used their teeth. The person who cut off his nose with a knife when left unattended was not participating in cannibalism. They aren’t literally feeding on their own flesh like zombies as the title might lead us to believe. For all the time Preston spent with some of these people who he grew to love, calling them cannibals for attention in a book title must have felt like a slap in the face. Although this was the most informative and fascinating chapter in the whole book, I was still left with a bitter taste in my mouth.
