12、se. On June 14, 1998, ABC news reported that an “Internet crazed“ Cincinnati woman was arrested for neglecting her three young children.

13、rapidly becoming an addictive source to a lot of its users. Users of the Internet include: students, housewives, and business professionals.

17、to get online. They put their lives on hold while engrossed with their computer usage. People who seem addicted to the Internet often show signs of psychiatric disorders such as, manic-depression.

18、had spent so much time online, that they were facing problems at home, job loss, and flunking out of school.
