I think this is as plausible as anything. I believe that it seems a little simplistic to be here for, what in essence is, a millisecond in the larger scheme of things and then just vanish to dust. Seems a bit brutal to me as well, mind nature is brutal.
I'd also like the idea of continuity and of past experiences, I know they are doing a lot of research into DNA memory now (not strictly the same thing I know), which would explain past life experiences/regression a little more in an alternative way to traditional reincarnation.
Only thing with that is, no kids and the memories die with you in theory. Makes popping out wee ones seem all the more important.
