from The New York Times:
Dr. Robinson and his colleagues tried to identify what activities happy people engage in. The study relied primarily on the responses of 45,000 Americans collected over 35 years by the University of Chicago’s General Social Survey, and on published “time diary” studies recording the daily activities of participants.
“We looked at 8 to 10 activities that happy people engage in, and for each one, the people who did the activities more — visiting others, going to church, all those things — were more happy,” Dr. Robinson said. “TV was the one activity that showed a negative relationship. Unhappy people did it more, and happy people did it less.”
But the researchers could not tell whether unhappy people watch more television or whether being glued to the set is what makes people unhappy. “I don’t know that turning off the TV will make you more happy,” Dr. Robinson said.
Still, he said, the data show that people who spend the most time watching television are least happy in the long run.

Absolutely facinating.
I guess people who watch TV spend less time doing other fun stuff, so while TV might not have a negative effect itself, maybe the fact people who watch a lot of TV aren’t engaging in so many other activities makes them less happy/they are less happy therefore take part in fewer other activities. Really interesting though, thank you for posting this!
Hmmm, I’m a little nervous about this info. I thought I was happy but I definitely watch TV probably more than I should. I can’t miss 30 Rock.
