Reason enough not to. Besides, we focus on redundancy in real life with computers, why not focus on redundancy with the body. 2 kidneys are better than 1, and even though 1 can do the job, if one fails, the other takes over. It's like having 2 fans on the server, one fails, other takes over. Why screw the balance up?
