I know a seceral people here where I live.
One is in very good health, still drives, I saw her a few days ago in the grocery store, and she was buying a gallon of milk. She lifted the milk like it was nothing. I see her out socializing a lot.
Two are in reasonably good health, but have some aches and pains, but then so do I.
The other 3 who I can think of need some help, but still do activities during the day, memory is ok, but not like a 20 year old. I don’t really know the 3 very well, they are each the parent of friends of mine.
20 years ago an employee of mine, his dad was in his 90’s and was very healthy until the end, he died at 99. Now, his son, my former employee, is 80, and still working part time.
