Coming to terms with death is a necessary adaption to the fact that we're all going to die in a fairly short time. If we had an expected lifespan of ten thousand years, then I wonder how many people would think that the way to "grow up" is to give up 99% of that time, rather than living those years and learning whatever lessons they bring. Perhaps, when the solar system is full of 5000-year-olds, they'll marvel that we infants were able to muddle through at all.
