My wife said: Every hour spent watching television takes 22 minutes off your life. She told me this while we were watching television. I almost choked on a cookie. Nearly proved her right. Twenty-two minutes. Could it be? She had heard this somewhere. Some study. It looked at how many hours of television people watched. How this sedentary, slothful activity affects our health. (I wanted to know what “sedentary” meant, but couldn’t find a dictionary in the digital TV listings.)
