The fitness fanatics on my FTS course are all dead of "natural causes"; so are the sports freaks who were on my first squadron (mostly ex-Cranners). We pi$$-heads whose athletic ambitions were no more than to be able to climb into the cockpit and pull the wings off the aircraft in terms of 'g' all seem to soldier on! Distant vision and 'g' threshold were the only factors that separated the men from the boys.
