Reincarnation: Is there an advantage for non-believers?

[reeay]

I grew up in a mostly Buddhist household and culture (except for my father who was a non-believing Baptist and us kids were not religious at all). Talking about re-incarnation was a dinner table/party conversation. Yet knowing one's past life didn't quite translate to anything more than 'oh how amusing, you were a ___ in your past life' for most people I know.
