If you want to die to assist the population-control efforts, be my guest. : )<p>More seriously, what would happen if the average number of children per family was 3.5, rather than 2.5 [1]?  Probably nothing absolutely catastrophic, and that&#x27;s roughly what would happen in a pessimistic scenario of an ageless society- instead of simply generating a batch of new people that will later reproduce, there&#x27;s a batch of new people <i>and the original parent</i>.  Maybe some outliers will just keep having children constantly (until they just physically give out- that would be an extreme strain), but I&#x27;d think most people would allow a decade or two between families.<p>More <i>more</i> seriously, birth rates are declining drastically in highly developed countries, to the point that many places are worried about population <i>decline</i>.  Overpopulation is a problem in developing nations, but realistically, anti-aging won&#x27;t make a big difference there- they&#x27;re already typically dying of <i>more  preventable</i> things than old age.<p>[1] Source; that old apocryphal statistic we all know from the 90s or something.  Its probably different now, but I&#x27;m too lazy to look it up.
