" Why don’t we all live for a longer time? On mountainsides in California and Nevada there are pine trees that were alive when Julius Caesar was wandering around Rome. Why do some organisms live for dozens, hundreds, or thousands of years while others, in the natural course of events, do not see even a single year pass? Death from accident or infectious disease is no puzzle; the puzzle is death from “old age.” Why, after living for a time, do we fall apart? This question is always lurking as the birthdays pass, but the short lives of the cephalopods make it vivid. Why do we age? "
