older guys and your health

I had a heart attack 11 years ago and heart surgery.I was walking 3 miles a day..even at 20 below zero F, playing hockey,cutting and splitting all my firewood for the house and shop by hand,mowing all the lawns with a push mower even though i had a J.Deere riding mower etc. etc....but was noticing problems prior to having it.Anyway i probably shouldn't be here as the staff gave up on me and as a last resort administered Super Clot Buster which saved my life.
There was damage to my heart.I don't like the heat now and don't have the energy i used to have and i am almost 65.
The writing is on the wall!
