I am a great believer in medication. I take Plavix and a beta blocker myself, and once you get used to staying away from sharp objects, you have it made. I have a resting heart rate of between 50-60, and that's cool unless you sit for too long, then you have a tendency to fall asleep.

The up side is that on even the most strenuous rides my heart rate will never go over about 140, which is verboten for me anyway.
