What about the relative lifespans of the astronauts? The ones selected to go to the moon were probably older, fitter, and more experienced when they made the trip. Did they outlive the other astronauts and the general population? Since mortality due to heart disease increases with age, did the moon astronauts just live longer?

Infact, Table-1 in the paper confirms this. The astronauts that went to the moon lived significantly longer (65 compared to 56 years).
