I must confess I do not watch TV at all unless I am dying to see a rented movie (which is rare).
But I wonder if the amount of time I spent at the computer is as bad as watching TV. If the issue is being 30 hours sitting on a couch, then sitting at the computer surfing the net, playing video games, chatting, etc for about the same time must have also negative health implications as well. Do you know of any study on this?
I think our modern world including Americans (children and adults) are spending too much time sitting at their PCs in addition to watching all those hours of TV. That is really bad!
