Evolution

Hypothetically, if all humans cooperated, we could increase our average/maximum lifespan, assuming we had enough time on an evolutionary scale. All you have to do is set a minimum age before being allowed to reproduce. Starting at 20 would already be pretty high. Gradually, after a few (hundred?) generations, start raising the bar to 21, 22, and upwards all the way to 50 if you like. Genes that were advantageous for long individual lifespans would quickly come to dominate. I'm guessing the ceiling could be raised pretty high...

Do you really consider us ignorant and powerless enough to have to depend on natural evolution?
