Some play themselves to death. Last year, the deaths of at least seven people were attributed to excessive game- playing. In August, a 28-year-old man died after nearly 50 straight hours of playing online games. In December, a 38-year-old day worker collapsed and died at an Internet café; his logs showed that he had played for 417 hours in his last 20 days. There are private telephone emergency services that dispatch ambulances for children who collapse while gaming or refuse to come out of their rooms, where they remain glued to online games or threaten violence at intervening parents. In South Korea, children get used to the Internet at early age. A survey last year by the Ministry of Information and Communication showed that nearly half of children between the ages of 3 and 5 use the Internet.
