If you want to make something useful with your TV, turn it off. That´s the best you can do. A staggering percentage of homes all over the World have television sets, of these, almost half of them have three or more televisions. Even more, it is most likely one of the televisions might be in the bedroom. It is advisable to remove televisions from bedrooms since it promote that we spend more time watching at it.
After giving these advice I must say that I have reduce the time I spend watching TV to the point that I don´t watch tv anymore... but I have change it for something else. Now I watch a lot of online series. Which is not good either. Even though now I read more, I go to the gym, I do some gardening and hang out with my friends more, I have decided to stop following some series. The series I will stop following are Outsourced and The Office. The series I will keep following are Modern Family, Raising Hope, Archer, & Parks and Recreation.
