Humans as Robots, How Cyborgs work?

       You have heard of robots. But have you heard of human beings with mechanical parts and electric circuits connected to the body? Cyborgs (Cyber organisms), as they are called, figure in science fiction. But prof. Kevin Warwick of England claims that he is in fact a Cyborg.
