it's called self control
unfortunatly in todays time this is not enough, think of it this way, all an alcoholic has to do is to stay away from alcohol what is in itself
quite dificult at times.
But in todays times it's litteraly impossible to stay away from the Internet.
Yes people are getting additect to the internet... and I can prove it.
My last job was a Managing position Customer support for the Online game World of Warcraft, I had a team of 80 Agents who would look after the clients who play Wow and their complaints.
We had daily complaints of people saying they would kill themself if we don't do this or that, for each we had to evalutate if they are real and serious if so than send the Police over to their house.
I have seen insane examples of people being completely consumed by the Internet and playing Wow, married couples who would play in the same house in separate rooms talking to each other over the game, asking each other if both are ready to go to bed.
We had a couple in scotland that didn't stop playing and didn't take care of their kids, they lost the kids to the wellfare because they wouldn't comply with the child wellfair office.
Countless of people that begged us to close the account of their loved once because they are ruining their life don't go to work anymore or school.
Wow is on the same list of addicted substances as Heroin etc. there are not real offices in Germany were you can get help with your addiction, more and more people recognice that this is becoming a serious problem.
I could go on and on about how examples of people I have seen that take Wow and online gaming so serious.
For excample one of my Staff who quite the job because I refused to let him work only the morning shift and not like the rest of the team shift work, his reason was... well I cannot play the game in my guild anymore and I cannot raid, he quite the job and according to his housemates didn't stop playing for 5 days, he eat drank and slept infront of his computer, he set the time in the middle of the night so he can do certain things.
I have seen so much more in the time I worked there... maybe I write an article once.
