"Internet addiction should be considered a true mental illness, according to a recent editorial published in the prestigious American Journal of Psychiatry. Jerald Block MD says excessive online gaming, porn surfing along with e-mail and text messaging are signs of mental collapse and “merit inclusion” in the Diagnostic and Statistical Manual of Mental Disorders (DSM V)."
"Block pointed to ten deaths in South Korean Internet cafes as sure signs of addiction. He adds that the average high school student in South Korea plays online games 23 hours a week and that more than 210,000 children required treatment for excessive gaming and Internet usage in 2006. Chinese figures show that 13.7% of teenagers are addicted to the Internet, according to Block.
