Count Iblis II,
i agree about the body parts. But if your brain were to be replaced, you would no longer be yourself.
Do you realise that 'you' have only been living for a very short time. what you percieve as 'you' is actually a copy of an older version of you.
say every atom in the world has it's own individual adress. A copy of you, would definitely not be 'you'! Even though they may act exactly like you.
