Italian surgeon Sergio Canavero is stirring up some controversy in the medical world by proposing that successful full-body transplants are only two years away. The operation itself is mind-boggling as it consists of grafting a living person’s head onto a dead person’s body, jolting the body back to life and then re-training the brain to work with its new limbs. Canavero insists the technology to make it work exists, but the true obstacles are ethical ones. Should the surgery be done and will people want it even if it’s made available? Time will tell and apparently we won’t have to wait long.
