I had a heart attack at 46 almost 47 six years ago. I had four stents. It slowed me down and I ride more laid back but I still get out there. Bought a Spot Connect, Life-flight membership, and try to remember a bottle of Nitro. I don't know if I would ride faster now anyway a body is bound to slow down anyway. I say,,, take all reasonable precautions,,, but never, never, never give up (Winston Churchill).
