If you took a long-term approach to extending life (albeit extremely long term), i've often wondered if restricting the minimum age for intial reproduction would result in evolution favouring longer living health.

What I mean is, if you were preventing from reproducing until say, 40, healthier 40 year olds would be favoured over those who suffer from "wear and tear" earlier. Over many generations, this could be gradually increased until we have a population of 90 year olds who are healthy enough to produce viable off-spring.

Makes sense to me. Those genetically destined to die young, if there is such a thing , would not pass on their genes etc .  As a collective we cannot even wipe out poverty on a planet with massive resources nevermind  deprive ourselves for the sake of future generations. Would we want to live in a world where we tell people they are too genetically inferior to reproduce. I know this is just theoretical though.
