WATCHING too much TV lately? That's just sad, man. No, literally:

Unhappy people watch significantly more television compared with happy people who are more socially active, vote more and read more, U.S. researchers say. . . .

The study, published in the Social Indicators Research, also notes that TV watching requires very little activity compared with other leisure activities. TV viewers don't have to go anywhere, dress up, find company, plan ahead, expend energy, do any work or pay for anything, the researchers said.
