Funny thing, but I feel younger now than I did in my 20's.
I have a part-time job, from 2 PM to 7 PM five days a week. Yes, I'm dependable, but the hours are wonderful, and I don't have to drag myself from a sound sleep at 6:30 in the morning! Work is a choice, not a matter of survival, and that takes a lot of pressure off as well.
During my working life, I almost never called in sick regardless of how I felt. Compared to my co-workers, I was the most dependable employee in the place. It counted for very little, IMHO.
I've also proved myself dependable when my daughter and granddaughter create crises and call on me to bail them out.
