And like Mad dog said, the test is very faulty.
I'm unemployed, and if I'm not out doing things (which is not often due to money problems), doing some household chores, or other "have too"'s I'm 85% of the time online, the last 15% spent reading.
Second of all, there is no such thing as an "internet addiction". Resently wrote a short essey on the stubject, and what alot of people classify as "internet addiction" is more of a compilation of other addictions and dissorders. It can be a mix of OCD, PGD, a game addiction, or several other things. But the internet in itself one doesn't really get addicted to, it's just the medium through which one get's the thing needed.
