Faced same question from many. Still do. Even from drivers still there at 40 yrs in and 70 yrs old. "I have to do something!"
"Not me".
I don't get bored easily. Been off for many surgeries, all of which nobody here would care to hear, and dreaded the time I had to go back.
My saying when I decided to retire and now: "I've got too many things to do that I want to do and this job gets in the way".
Been gone 3 yrs now and not ONE day goes by that I wished I'd been able to do it sooner. Nope, no job, no pressures, no alarm clock, no nothing. Well, with the exception being that I DO worry if the local watering hole runs out of Vodka. Now, we have a problem.
