Clunkdriver,
That may well be the case. However, I am afraid the data you are providing is not exactly relevant to the discussion. Statistically there will always be a certain percentage of people who will die of whatever cause before their 65th year because they are, as you say, blessed with those type of genes.
However, I'm pretty sure that both of us will agree that in any population the odds of people dying on the job are dramatically higher if your population is exclusively above 65 compared to a population that is say 20 to 65 years old.
People get old. With old age, the risk of death increases. At some point it's time to retire I'm afraid, especially in an industry where the lives of people are dependent on you. I can understand that people might wish to continue working, but a line needs to be drawn somewhere.
