Well, sorry, but I reckon that's utter bolleaux. Because back in the more gentlemanly days of the 70s and 80s when very few aircrew indeed committed jockstrappery, we were hardly dropping like flies. And the only people who were off sick regularly were the jockstrappers.

An oft used but spurious argument. We can all cite examples of people we knew who smoke 20 a day, did no exercise, and lived till they were 90. Equally, I know jockstrappers who have died from heart attacks and suffered from cancer.
The research, carried out on larger populations than RAF aircrew, shows clear evidence that those who exercise regularly live longer, are less likely to suffer heart disease etc etc (see previous posts).
