Computer Addicts Definition

Defined by some mental health experts as individuals spending, on average, 38 hours a week online, compared to the nonaddicted types who spend, on average, five hours a week online. Computer addicts allegedly also neglect loved ones and chores and have odd sleep patterns—reflected in daytime sleeping patterns to compensate for heavy nighttime online usage. Young, K.S.
