You certainly have a point about not being perpetually tired, MacGuy. That's got to feel good. Seems as you get older, even flying good trips, it gets harder and harder to recover. But I don't think its's specific to flying freight (except for night flying), I doubt those flying pax day in/day out are feeling any better. Living out of a suitcase, hotel life, long days, irregular hours....I won't miss that. Coming home, I just empty out the dirty clothes and don't even bother to unpack.
