In theory, at least, we might achieve a certain sort of invulnerability right at the end of life. Suppose that under favorable circumstances we can live a certain number of years, say 125, but no longer, and also that we can make life as a whole better and better over time. Under these assumptions we might hope to disarm death by spending 125 years making life as good as it can be. If we were lucky enough to accomplish that, afterwards (...) we would be immune to mortal harm. Especially for those who are closer to the beginning of life than to the end, however, this strategy leaves much to be desired. It is like devouring an entire banquet so as to eliminate the danger of someone stealing it from us. Like a feast, a good life is safely ours after it is over, but then safety comes too late to be of any use to us. To be of practical value, we need protection from mortal harm much earlier in life.
