Thanks for all the input so far, and keep it coming!
I should have been more clear that yes, I was specifically asking those who HAD to retire because of health issues.
My granddaughter (18) said to me, "You must be so excited!" She's so young. She couldn't be expected to realize that it isn't a happy thing not to be able to do the job I love any longer.
However, her comment did trigger something in me, and I'm trying to ease over to her perspective and see the exciting things about being retired. (I didn't mention to her that she might have to support me someday, so she should get a really good job.
