I quit
After three attempts, I finally did retire. Now sleep soundly at night, at home in my own bed, instead of staring blearily at the rising/setting sun. Don't have nightmares about getting through JFK (Immigration won't let you in; Security won't let you out). Don't have to eat junk meals, stay in junk hotels and perpetually dispute the roster with some mean-minded lamebrain in crewing. Enough. Good luck, people.
