We see that the same.
My grandmother lived to be 98, my father is 93. My mom’s aunt lived to be 97.
It can be done. The 97 year old aunt of my mom, was as sharp as a tack. Had her memory right to the end.
I’ve got too many things to do to quit now. smile.
My Grandmother lived to be 94; was running her household until 5 months before she died. Her daughter did almost as well. And I believe it was entirely due to the fact that both of them maintained very active interest in the world around them, and in their hobbies and personal projects.
I’m very glad that you still have your Dad. I’d dearly love to still have mine.
