This is one of the most ridiculous things I have ever read.
Next they'll be saying that every interest and hobby is a dirty, nasty addiction.
So I suppose watching sports on the television is an addiction? I know of men and women who watch it EVERY chance they get. They talk about it EVERY chance they get. And when they are not watching it or talking about it, they are playing sports related video games. Yep, guess Sports is an addiction too. Perhaps we should study 2,000 people to see just how much time they spend involving themselves in sports related things.
Ahh, but here is the thing. Society as a whole accepts sports as being healthy and good for you. You get exercise, interact with people, and develop team work. Yay! (Not)
Sure internet involves not doing much activity and leads to a lot of negative outcomes, but so do a lot of other things. Sports, for example, can lead to life altering injuries and addiction to drugs and/or steroids.
But hey, society is apparently all-knowing and if they say that it is good for you, then I guess they think we should all be lemmings and just go with it.
