No, You Probably Won't Drop Dead While Exercising

Dropping dead while exercising is a common fear, especially among middle-aged men. Unfortunately there have been limited data on the precise rate of sudden cardiac arrest (SCA) in middle-aged people and little understanding about the medical history of the victims of SCA. Now a new study fills in some important gaps in knowledge and shows that this fear is largely misplaced, given the small risk that exercise will lead to sudden cardiac death in most middle-aged people.
