Not all television is vapid horseshit, of course. I just think it's important to realise when you're watching television for no other reason than to watch television. Once you're firmly in this circular hellhole of channel surfing and time wasting, it's a difficult habit to break. Picking and choosing the shows of quality and watching only those, while filling your time in greater pursuits is optimum, I believe.
Vegetating occasionally is fine, but we live in a world where people are transfixed by television, and it's a tad sad.
