Technology these days are incredible, especialy when put to good use for body parts after amputation... I belive you can get more experience from these things, I wouldn't mind a full prosthetic body, it means your strength is 10x more powerful than your own body, just think if you got full prosthetic body for legs you'd be running around a lot faster and not tire out so easily. Cyber Brains may well be the next part of evolution to survive for those who have half a brain... or no brains x3, and your brain can link to an online Cyber world and communicate with anyone around the world.
Good thing about Prosthetic bodies is, it can help those who are paralized from the feet upwards and be left with 1 un-paralized arm, or paralized from waist down, for those who are stuck in wheelchairs they'll get very board and sad, just because of an terrible accident which costed them an arm & a leg.
