> Like what? Take any norm breaking innovation in the pass 2000 years. Any idea that sounded arcane at its time: Earth is not Flat, its not the center of universe, light is a wave and a particle, etc. Perhaps decision was not the correct word to use, "ideas" would be better. > What kind of prediction is that? A prediction like any other. I think we tend to become risk averse as we age, risk averse people don't like changes, without change you don't have a chance to fail, or succeed. If people to live longer I would think that every other stage of life would start to stretch. Take presidency as an example, its a four year cycle. If life expectancy was 200 years, would it not make sense to have presidents for 8 years? Would you retire after 30 years or 60 years?
