There is a slim possibility that your donated head will be the head, the head that holds the key to the mysteries of the twenty-first century’s great disease epidemics. But it is equally possible your body will end up being used to train a new crop of Beverly Hills plastic surgeons in the art of the facelift. Or dumped out of a plane to test parachute technology. Your body is donated to science in a very . . . general way. Where your parts go is not up to you.
