Another thing to consider is that pilots who were hired within the last decade haven’t had to pass an elaborate physical, only needing a Class 1 medical. As a result there are quite a few diseases one could have had as a new hire that may not bode well for longevity. It will be interesting to see how long the pilots of the future live, and until we get there, we really don’t know.
Longevity, as a metric, is important as it correlates with mental decline, so let’s look at how the US does in the latter. Not too well. We are in fact #8 in Alzheimer’s & Dementia deaths, with no “fly beyond 65” countries worse than us. See link:
