I think the exact same way... my Great Aunt lived to be 104. A great uncle lived to be 101. My grandmother is 95, and she still speeds in her little Plymouth Reliant
About 6 years ago, she was taking care of my ill grandfather who was suffering from a long staff-infection-related illness. Just picture a very petite 90 year old woman literally carrying a tall, average-built old man around the house.
She still shovels snow and rakes leaves to this day. Amazing how some people grow old like that. And Happy b-day to your grandmother
