I disagree. There can only ever be one true *you* and everything else will be copies of you. If a duplicate of you were to be made whilst you were still alive, you would still be *you* as an individual and your copy would be themselves as an individual. If you were to die, your copy may think, act and look like you, but your mind wouldn't suddenly jump into his (hers) body. *You* would be dead, and an exact copy of you would be alive. Hope you can follow that without trouble.

P.S. For future reference, are you male or female?
