Death isn't an unanswerable question. It is, in a world with finite resources, a necessary inevitability. The only question is whether that death comes in orderly cycles, or catastrophically.

Not everyone wants to live forever. My grandparents lived to their 80's. My father, who is a bit over 60, considers that to be a very reasonable number, and I feel the same way. I don't want to still be here in 60+ years straining the resources of my daughter's generation.
