Sure to a certain point. But there’s a limit to how much extension one will get just from that. Assume for example that post infancy there’s a 2% chance of random death due to violence, disease etc. in the native environment. Then there’s about a 3/4th chance that they will survive to age 75, assuming a rough constant. Given that, there’s little evolutionary incentive to push mortality down much past that. This is of course a toy-model, but the basic point is sound.
