Hey good point about the 100 years, General. We may find the 'shut-off gene' any time now. That is the one that instructs cell lines to die. If not in this lifetime, then maybe the next one, we will be grappling with a whole new set of issues surrounding immortality.
If you ever read Lord of the Rings, you see from the Elves that it really comes with a lot of baggage to live essentially forever.
