More Heart Attacks & Strokes While Watching Sports

A new report claims rooting for your favorite teams on TV can be deadly.

Researchers at the University of Montreal believe watching sports increases the risk of heart attack or stroke.

That's because the stress it puts on the heart is the same as a hard workout.

A study found that heart rates rose by 75% when watching sports on TV, but when going to a live game the rate rose by more than 100%.
