You think you spend too much time on the Internet? In Korea it's common for youths to log on for 17 hours a day. Beyond skipping school to be online, people have started dying from exhaustion.

Its latest effort is the Internet Rescue Camp that subjects campers to physical challenges, like ropes courses, in the hopes that it will help them kick the Internet habit.
