In a Jiff -
TV is an interesting topic. Time with a TV can be quite productive, as when someone watches documentaries to learn more about an area they care about. They can learn more about autism to help care for an autistic child. TV can also be mindless though, when someone sits through commercial after commercial. The average adult, by the time they hit age 65, has spent two YEARS of their life watching commercials. That is just staggering. If we were given a free 2 years, would we choose to spend it staring at commercials?
So definitely if nothing else people should go for commercial-free living as much as humanly possible. That's a start.
