SJS, nothing could be farther from the truth. Improper use of the internet harms marriages, families, friendships, and more. Not just the person who uses it.
Smoking DOES cause health problems for both the smoker AND the people in the area.
Improper internet usage CAN break up marriages, families, friendships etc. To be fair, I don’t actually know anyone whos marriage or anything broke up from the internet (though I am not saying it doesnt happen).
Perhaps the marriages more likely to be broken up by the internet are those where internet is taboo?
