"It's not the sweaty type of exercise we're losing," says David Dunstan, a researcher at Baker IDI Heart and Diabetes Institute, Melbourne. "It's the incidental moving around, walking around, standing up and utilizing muscles that [doesn't happen] when we're plunked on a couch in front of a television." On average, most of the participants had about 30 minutes of exercise per day.

The American Heart Association journal says Americans average 5 hours of TV a day.
