I flew with a 59.5 Capt for a month who was a great person, but I can tell you it's definitely time for retirement. Fortunately, he's ready to hang it up in a couple of months. Every person is different; it may be time to retire at 57 or 63 or ? depending on how you still hack the program. Personally, I'm looking at 58 for me, but need to see how things flush out (or down).

I'm with Jolly, too.
