Surgeon General Warning for watching television

Why shouldn't the Surgeon General insist on a health warning to be broadcast before every television show?

Recent research has concluded that sedentary screen time can be deadly:

 They found that each hour a day spent in front of the television increased the risk of death from all causes by 11%.  From the Guardian

So television is responsible for more deaths than all illegal drugs.  But the media industry has better lobbyists.

Incidentally, this same article from the Guardian shows a math-challenged reporter at work.  In the lede, the reporter wrote:

Every hour spent watching television each day increases the risk of dying from heart disease by almost a fifth, say scientists.

So 11% is almost 20%?

Please excuse me while I step away from the computer to take a walk.
