My parents are in their 80's, and the walk several miles everyday. They can out walk me, and I am on 51! :smile: The doc says my dad has the heart of a 25 year old.
Smart folks. No wonder they have such a brainy son! :smile: Do it NOW, so you'll be able to do it in your 80s, too. Yeah? That's nothin'! I'm 74 and my doc says I have the brain of a 10-year-old. :smile: (just kidding - congrats to your dad.) J.
