I guess my parents are outliers. My Dad worked until his 70's until basically forced to retire. He's in his mid 80's and in decent health for his age. My mother otoh is in her mid 70's and not in such good shape. It's been 2, 3 years since she retired. She's actually now in worse shape since retiring, since she is not moving around, getting out of the house as much because she doesn't have to go to work.
In either case, I have no problem working and keeping busy past my ideal retirement age (62) but it would be nice to get to point of not HAVING to work, and then I can entirely choose how my day is organized.
