My father had a MASSIVE heart attack when he was 53. They had to jolt him back to life 5 times.

At that point, I decided to have my heart attack on the installment plan. I would hurt a little bit every day on the bike in order to avoid the big hit of a heart attack. In those early days and months, there really was some pain every day. I hadn't ridden a bike or run for a long time. But now, 26 years later, the bike has kept the promise. I'm still racing the bike occasionally. Not as fast as I once was, but still enjoying the journey. And there has been no heart attack. 10% body fat and, sadly, more fit than my kids.
