This. If anything, evolution would seem to select for lower longevity so more breeding sooner (assuming that if we live longer we would put off breeding until later, which may not be true, and if it is, is probably only true with contraception). And, of course, the oft-repeated "anything that happens after reproduction is irrelevant to evolution". Which isn't 100% true (it takes a village to raise a child, after all).
