If I died, which structures of my brain to be rebuilt would let me know I'm back? If someone creates another brain with the same structures as I have, will I have the feeling that I have two brains? I mean if the body that the brain controls was hurt will I feel his pain? If the body is making love, will I feel his excitement? Can I feel all his desires, passions, happiness, fears, etc. etc. If I can't, then where is my selfawareness really from? The unique materials which form my brain? But won't my metabolizm interferes that? I'm really bewilldered! In short, If I die, will my selfawareness vanish? If it will, will I get all my feelings back ever, naturally or artificially?
