And if say, hypothetically - you do not possess undies, not even in a hidden stash, for whatever particular reason, would these racoons leave you alone?
I just meant that it wouldn't really matter if we got you a new body or glued you up from eggshells, neither would be the same "you" as before. (Though if we're being optimistic here both are still you)
Going by that logic, your body exchanges atoms with the air and other things all the time. You are made of as much you in the past as a grape is made of a banana
