As long as I could still croak, permanently, after my second life is over, hopefully around 80, I'd like to come back as an incredibly well hung billionaire. Incredibly because there's a difference between well and incredibly, and billionaire so I could live a great life while still giving to all of the charities I want to. 1 billion is enough. With what I'd give away, neither the charities nor myself would be disappointed with what we get.
