More and more teenage addicts in Korea are refusing to leave their bedrooms and some young adults are playing fantasy games online until they literally drop dead. "He didn't adapt very easily into high school," said Chu Dong-jiu, whose son, Jae--yun, 17, cruises football websites 12 to 14 hours a day. "That was why he dropped out. Now he spends all the time he is not eating on the computer. He hasn't been out of the house for eight months."
Eighty percent of South Koreans have broadband internet, the highest rate in the world. In Britain the figure is less than a third. This is partly the result of its intense, science-based schooling.  But according to Dr. Kim Hyun-soo, chairman of the Association of Internet Addiction Psychiatrists, an "education frenzy (狂怒)" has undermined children's self-confidence and forced them to seek escape elsewhere.
Children, many tutored beyond school, enjoy little free time outside home, driving them into the solitary solace(安慰) of the computer, he said. “What children do on the Internet reflects what they want in reality,” he said. “The dreams they pursue are the dreams they would pursue in ordinary life.”
The most common obsession(迷住，困扰) is with online games in which players become fantasy figures in landscapes pitted with foes and obstacles. One 28-year-old young man collapsed and died last year after playing a game non-stop for 50 hours in an Internet cafe. Doctors said he died from exhaustion and dehydration (脱水). Studies show five percent of "gamers” are seriously addicted, with a further 15 ~ 20 percent betraying signs of an unhealthy obsession. Gamers make up 90 percent of Dr. Kim's patients, often referred to him by mental hospitals to which parents had taken their children. The other l0 percent are guilty of freakish (异想天开的)and anti-social behaviour on websites. "These people are very frustrated inside and full of anger," he said.
The government has stepped in, banning children from Internet cafes after l0 p. m. , and sending teams of psychologists to visit them.
