Food for thought.

If a person is smart, they don't watch television at all, except for news or other interesting programs (which are very rare). If a person is a fool, they watch television constantly.

The more a person watches it, the more foolish they become.

That's not true; there are a lot of interesting programs and movies on television. If you want, I can give you some examples: Galileo, Aviators, Top Gear, Glavnaya Doroga, MythBusters, The Smartest (not all of them), Heroes (I like it, IMHO), Smallville. There used to be a movie on the Zvezda channel about airplanes and how aviation developed in our country. On the Rossiya channel, they often show films from the 19th and 20th centuries about secret weapons of that time, what problems there were, and so on; in general, it's a documentary film. Most of them are shown constantly; I don't think I'm a "fool" according to your definition. Because I learned a lot of interesting things from them, and I just enjoy the movies!
