Add television to your list of dangerous substances! Watching TV can decrease your life expectancy. British researchers looked at the TV habits and chronic disease risk of 11,000 Australians.

The surprising result: For every hour in front of the TV, life expectancy drops an average of 22 minutes! And the average American spends almost three hours in front of the TV. So start cutting down on those beloved reality shows today, and go for a walk instead. You’ll squeeze some fitness into your day and return with a healthy glow on your face.

The Kardashians will unfortunately still be there when you get back.
