Yesterday a nice looking guy stopped me in a supermarket and asked “Are you the book guy?” I was and, of course, he turned out to be a fan. Here’s the thing: he had been a dedicated runner all his life and, with YNY, had added some other things to his regimen. And despite a terrific life style, he had lately had serious heart arrhythmia and was soon to have an operation.
The point: doing the YNY stuff improves your chances radically. But there is still some bad luck out there. The moral, to the extent there is one: get back into the exercise mode as soon as you can after a rough patch. It will help with recovery. But there is still such a thing as rotten luck.
