Doubts? Doubts? You got doubts?
The caption on the photograph below might cause doubts. It reads: "Dr. Ren Xiaoping ... an orthopedic surgeon in Harbin, China, plans to transfer a living person's head to a new body. Photographs on the walls of his office showed his experiments with similar transplants in mice. The mice lived only for a day."
Mr. Wang is currently paralyzed from the neck down. I guess he figures it's worth a shot.
