jonjuan,
I have a friend who flies for FedEx. Man, he is really raking it in! And you should see the gargantu-house he just built with his own private runway to use when he plays in his Stearman and T-6!
BUT, he's 48 and looks like he's 65. The years of long nights, always running his body against its natural circadian rythem, have really taken their toll on him.
I'll take my 'measely' $132K/year (with O/T and holidays will bring me close to $160K, plus full medical, a great 401K, and 4 weeks of vacation a year, and living almost wherever I want without a commute, just to name a few perks) and normal aging and lifespan over his paycheck and lifestyle, and premature aging any day of the year.
