Experts warn that Internet addicts are getting younger all the time.

Tao Hongkai, a high-profile campaigner who toured around 20 provinces and cities talking about the seriousness of Internet addiction, once said the youngest patient in China was only two years old.

Without confirming that fact, Tao Ran, the director of Beijing-based China Youth Mental Health Center, told China Daily that Internet addicts fall into two extremes -one is more young preschool children, the other promising college students.
