PARIS — Once, while watching a late-night rerun of “Big Brother 17,” or maybe it was “Big Brother 7,” a nearly finished pint of Häagen-Dazs on my lap, I wondered: Is this shortening my life?
Now, thanks to a study by researchers in Australia, I know that the answer is yes. Watching television may indeed be hazardous to one’s health.
The report, published last week in The British Journal of Sports Medicine, says that every hour of television, after the age of 25, shortens the viewer’s life expectancy by 22 minutes. Adults who watch six hours a day may be cutting almost five years off their lives — almost as much as if they were lifelong smokers.
