[Sephus]

i have no expertise in this area but it seems very unlikely to me that none of the matter that composes my body was "there" when i was born, not that i think it's all that important to the question.

i think the answer is a definite "no" but it's a mysterious question. for example disassembling your body obviously "kills" you, so if the new version of you really is "you" it should seem to you that you fell asleep and then woke up. but what if it makes multiple copies of you? they are identical people (except for their physical location) but they aren't all the "same person."
