Internet addiction is not a figment of our imagination, researchers in Germany say. Over the past years, the researchers have interviewed a total of 843 people about their Internet habits. An analysis of the questionnaires shows that 132 men and women in this group exhibit problematic behavior in how they handle the online medium; all their thoughts revolve around the Internet during the day, and they feel their wellbeing is severe­ly impacted if they have to go without it.
