I had triple bypass and an unknown heart attack at 49 and now about ready to turn 53 with no problems . Still farm , still work in town , after the surgery and rehab I felt better then I had in a long time . I smoked at the time and quit when this took place and never looked back . Keep your mind set right and you can come back stronger then ever ! And yes I still scoop snow and clean out bins , they say you wont run a chain saw either but I cut wood for the shop every winter. I help pick up a few square bales each year to grind for the cattle. Good luck and let us know how your doing !!
