I am neither old nor young, and if longevity escape velocity becomes more of a possibility, one wonders how the phases of life (currently, generically all in about four score : grow, learn, explore, partner up, build/contribute, consume & produce, enjoy, regret, reflect, die) will change?  Beyond merely repeating or even morphing, could entirely new phases of life for humankind (or whatever cybernetic beings we may become) emerge?
