Need a reason to watch less TV other than wasting time…Check out this post from Sharp Brains blog (great blog, check it out here)
Watching TV five hours a day has an effect on your brain: it trains one’s brain to become a visual, usually unreflective, passive recipient of information. You may have heard the expression “Cells that fire together wire together”. Our brains are composed of billions of neurons, each of which can have thousand of connections to other neurons. Any thing we do in life is going to activate a specific networks of neurons. Visualize a million neurons firing at the same time when you watch a TV program. Now, the more TV you watch, the more those neurons will fire together, and therefore the more they will wire together (meaning that the connections between them become, physically, stronger), which then creates automatic-like reactions. A heavy TV-watcher is making himself or herself more passive, unreflective, person.
