In a human hand there are 27 bones. Some apes have more. A gorilla has 32, five in each thumb. A human has 27. If you break an arm or a leg, the bone grows back together by calcification. It will be stronger than before. If you break a bone in your hand, it will never recover completely. Before every fight, you’ll think. In each slap, you’ll think. You’ll be careful. But at some point the pain will come back. Like needles. Like glass splinters.
