When I was a little kid my father used to ask me a question. He would say what's the one thing all people have to do, and the answer (well, there were two answers) was, 'die and pay taxes.' I remember arguing that you had to be born in order to die and so, in fact, there were two things that all people had to do (excluding filing a tax return) and those two things are living and dying. But according to Ray Kurzweil, in 20 years from now dying wont be on the required list of things for all humansto do.
