There's no shortage of research showing links between watching too much television and early death. But what is it about vegging in front of the box that is so bad for you?
Sometimes it seems as though everything that's enjoyable in life is bad for your health, and television is no exception.
A number of studies have found links between watching television and premature death, and the more you watch, the more it reduces your lifespan.
It's been estimated that once you're over 25, every hour of television you watch reduces your life expectancy by close to 22 minutes.
While you don't need to give up TV, the Spanish researchers (and other experts) say you should limit the amount of time you spend watching TV to less than one to two hours a day.
