Here you go @[606028898:2048:Jason], this might give you heart (ha). I did a lot of endurance exercise as a younger man, and developed atrial fibrillation, have always wondered if it was related. Cyclists often develop it too. Extreme exercise has become even more popular, as a kid I barely remember anybody I know running a marathon or triathlon for example, or cycling 50km. We live in an age of extremes.
