To use all the old metaphors, Tris Dixon’s “Damage: The Untold Story of Brain Trauma in Boxing” is a slap in the face, a punch in the gut, a kick in the groin. Given that this remarkable, long-overdue treatise on the mental and physical ravages of boxing doesn’t hold anything back, it’s fitting that Mr. Dixon’s book lands with power and precision. For boxing fans, it’s a wake-up call. To remain a fan of the sport—to cheer on the punishment that takes place in the ring, then choose to ignore its consequences—constitutes a cruel form of enabling.
Even for readers who are not aficionados of the sweet science, “Damage” hits hard. At its core is the public adoration of athletes as modern-day gladiators—or, at least, icons of physical prowess—and what we demand of them: the courage and sacrifice that we celebrate from the peanut gallery. “This is a sport in which bravery can be measured by the amount of punishment one can withstand,” Mr. Dixon tells us. Meanwhile, in the ring, “bravery” is a surefire prescription for chronic traumatic encephalopathy (CTE), a deterioration of the brain caused by repeated head trauma.
