For me, the possibility of it connects up a lot of dots, and it's actually only very recently that I've begun to feel that there's something to it, even though I've been interested in Buddhism and some New Age stuff for years. I don't even think that it'd be proof of some kind of afterlife - just life, period. The fact of life, the essential energy of life. I don't see that it's physically possible for something to become nothing, but it can change of course.
