But a biologist might also point out that neurons rarely get replaced. If you are 50 years old you've got the same basic set of neuronal cells that you had 30 years ago. So you get a new skin every couple months but your brain lasts pretty much your whole life. So the quintessential "you" doesn't ever get replaced (at the cell level).
