Life-span

What about time? What about those 80 something years we have on Earth? Imagine a life devout of time pressure. When choices are not defined by their relative weight on the future. Imagine a double life-span.. say 160 years. 30 years of childhood, 30-40 years of youth, 30-40 years of adult life and then seniority. You'll have plenty of time to live through each stage of human life, to learn, to experience and not hurry up to prepare for the next episode. Plenty of time to decide what do you want to do with your life, plenty of time to waste in whatever makes you happy. Life would be less valuable. Days would stop reminding us that the clock is ticking. May be we would be less inclined to make stupid choices just because there is no time. And there will be a completely new class of problems.
I would never want to live forever... just longer. “Life is short” people always tell you “Live it up” and all that jazz. I am wondering how life would be with more time on our side. Or with no time at all....I guess people will start saying “Life is too long, better have some fun to kill the time”
