More'n likely you'd just create an alternate timeline where you never existed. But hey, if you ever get the chance, lemme know... or not, if I'm wrong.

Anyway, it's possible to completely remove somethin' from existence, whether you want to call it erasing or making it Nothing or whatever. Seems like, even if there's absolutely nothin' left, you can still be brought back.

Also, the medical treatment's great now, but it's not perfect. Get yourself banged up again an' you might be out of commission for awhile. Just a little friendly heads-up.
