You'd be surprised at the responses you get. I've had people get offended for suggesting some part of who they are is more or less chemistry.
Well, it's complicated. Personal identity may be in part a function of chemistry, but if you subject an entity to a lot of chemistry changes and change their desires as well as behaviors, it's difficult to say that the person is the same entity anymore, in any meaningful sense. What I mean is, just because chemistry might constitute identity, changing the chemistry need not alter the identity, but instead supplant it. If that's too vague, then imagine replacing the bricks in your house with steel, knocking down some walls, and converting it to a wigget factory. It's not your house anymore, just as the consciousness of such a radically altered human would not be the original's mind anymore.
That is, if there is anything that we can call identity anyway. Maybe there isn't.
