content: Technically still a head transplant since the head is the thing being removed and attached I believe. But since he is transplanting his head to escape the disease destroying his body, I would consider it a body transplant, whereas if somebody was transplanting their brain into another skull because of some medical problem with their head, I'd call that a head transplant, but I'm not a doctor so nobody cares what I would call it.  Plus it sounds way cooler to call it a head transplant.
