years ago I was mowing the yard at my parents house , I was in my twenties and stopped by to work on my dune buggy with my dad .
and sometimes I got to do a few chores when I visited for some strange reason ?
A neighbor lady came running out of her house screaming at the top of her lungs "HE IS HAVING A HEART ATTACK" as I was mowing .
Dad and I ran over there and found him on the floor in the living room blue and unresponsive , we took turns doing CPR on him until the ambulance got there and got him stable ,they said this about that ,you guys just saved his life !
He came home and lived a few more years before he had another one and this last post reminded me of that event, you might very well prolong another's life if you know what to do when and how .
