I've always like this set of thought experiments, ever since I read about them in "The Mind's I" (edited Daniel Dennett and Douglas Hofstadter) The conclusion I come up with is that the Buddhists are right - our sense of self is a bit of an illusion, and we can only really assert our living in this moment. We're these Hofstadter-ian self-aware "strange loops".
And one day we won't be. And that is tough to deal with. (Buy my comic! -- haven't started publicizing it yet :-D )
