I've thought a lot about the possibility. I don't find any reasons to believe it though. If there was an "afterlife" through reincarnation then there would be a continuum... memories. Otherwise what would the point be? Also there would be a very long line at the reincarnation gate We will always be a part of earth. I suppose that will have to be good enough.
BTW I also always envisioned myself as a future suicide. Many years later and it hasn't happened.
