Just saw this on BoingBoing:
A 28-year-old South Korean man died of heart failure after finishing a 50-hour first-person-shooter gaming session, according to Reuters. He was in an internet cafe, having apparently just completed his more than two day session (punctuated by breaks to go to the toilet and take brief naps on a makeshift bed). Upon failing to return home one day, his mother had asked the man’s former colleagues (he recently quit his job to devote more time to games) to find him. When they did, he told them he would finish the game and go home.
The cause of death was reported as heart failure.
