Organ transplantation personality changes are not about happy one day and sad another day.

Wrong. You can also not swap out your body and remain yourself.

> You can have shifts in your personality and still be you.

When do you stop being yourself? What makes you yourself? Think about it—it is not an easy question to answer.

Why not? Even taking technological limitations into account, there is almost no part of your body that can't be swapped out even today. People have artificial limbs, artificial hearts, artificial ears. They get lung transplants, kidney transplants, face transplants. Give the technology a few more centuries and I don't see any reason why a complete body swap-out should not be possible.

Indeed. But most people would agree that you can get an organ transplant or an artificial limb or a hearing aid or wear glasses -- or any combination of the above -- and still be you. Not so for a brain transplant.

Want to try it?

I do not think that is relevant in any way. Most people also believe in God; that does not make it a compelling claim.
