I can't help but think about solar radiation when I read this thread. Although circadian rhythms are an important consideration, so is excessive solar radiation. So I wonder (and I don't believe it is known yet) whether we are simply picking our poison. I can only conclude at this point, that being a pilot is not a healthy profession.
Considering that we have to work for peanuts at some insulting regional for 5-10 years just to get a chance to buy a lottery ticket for SWA or FedEx, perhaps I should abandon this logic-based commentary, since none of us can exercise any of that characteristic anyway.
But I digress . . .
I would evaluate a job on these measures:
1. # of days off per month minus commute time (basically, time at home)
2. $
3. Benefits (Health, Retirement, Travel)
4. Kind of people working with
5. Company's ability/desire to keep it that way
