As for people dieing after strenuous activities, I think it has to do with all the adrenalin running around the body during the activity. The adrenalin makes your body work a lot better then without. If you are on the border, like this guy might have been, the adrenalin keeps you going. When it wears off, you crash. This is pure speculation as far as Andrea Pinarello is concerned, but I have seen it happen to others. You see a lot of things running on an ambulance for nineteen years.
Aren't those electrical signals derived from the brain though? I was under the impression that any muscle activity, voluntary or involuntary, including the heart, was under control of the CNS. Is that not the case?
