I mean cutting the head of someone and attaching to a different body.
Before making your post, you should know that it was already successful with animals. Specially monkeys 30 years ago. Experiences were made in Europe and US. Sure it was not a complete tranplant because even today you cant fix broken spinal cords. But the monkey survived like a paralyzed person for days, moving eyes and trying to bite. Finally dying because the body rejected the head.
