My Grandma (father’s mother) lived to be 98. She was rock solid up until about 96. She was religious about her 30 minute morning walk, 30 minute afternoon walk, tending her small garden, being social, and “stay off the damn couch”.
She had a fall and broke her hip at 96 and never quite recovered. She was a force of Nature her entire life. She passed 10 years ago and is legend in the family. It seems everything is still measured up to her.
That was her secret to long & healthy life...daily walks!
