It provides a mixture of military-style physical exercise and rehabilitation. The teenagers climb over assault courses and learn how to ride horses as well as participate n workshop such as pottery and drumming.The aim is to cure them of their obsessive use of computers in a country with almost universal internet access. Concern over compulsive internet use in growing in South Korea where 90 oer cent of homes have high-speed broadband connections and some online games players die form exhaustion after playing for days on end. Psychiatrists estimate that up 30 per cent of South Koreans are at risk of internet addiction. The rescue camp in woodland near the capital Seoul treats the most severe cases- They're all male. During the 12-day sessions participants can't use a computer and can only use their mobile phones for one hour a day.Lee Yun-hee, a counselor, says that the priority of the camp is to provide them with a lifestyle that has its roots in the real world- not the Internet. She says, "Young Koreans don't know what this is like"One participant , Lee Chang hoon, regularly spends 17 hours a day in front of the screen, surfing Japanese comics and playing a roleplay game called " Sudden Attack".He usually plays all night and misses school to catch up on sleep. Three days into the physically challenging programme he says," I don't have a problem- seventeen hours a day online is fine". A few days later he seems to change his mind. " I'm not thinking about games now. Maybe five hours a day online is enough".
