You start out at age 78, and then life only gets better and better for you. And then "You're not scared of dying because you're now a baby so you don't know what's going on anyway...When its a baby everybody is around it going, 'yeah its gonna die soon.' But the baby hasn't got a clue, its happy. Its playing about with its rattle or whatever, it's not scared."
I wish I could find the part where he decides people should have little apple pips in them, because that kind of fits in to this too.
