A ''mind'' independent of the physical structure of the brain doesn't exist. If such a thing did exist then physics at the level of atoms would be incomplete.

According to Quantum mechanics all particles of the same type are identical. Your electrons don't carry the label: ''use only in Rob's body'' Consider this thought experiment. A surgeon is operating on you. He will repair injuries in the usual way, but he may also do some experiments:

1) He will remove some uninjured body parts and then put it back, if done perfectly this shouldn't have any effect.

2) Remove uninjured body parts, copy them and put the copied body parts back. This can't be any different from 1).

3) So, if he just removes all of your body parts and replaces them by copies then you would still be the same.

In fact, such replacements happen all the time at the molecular level. The atoms you consist of are being replaced continuously.

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?
