Hmm, so many points to make.
1. What a loser. Playing WoW until you go into convulsions? You'd think he would have realized he needed to stop somewhere before that point. Loser.
2. It was only 24 hours. I've never quite reached that but I would have thought somehting like this would have taken a bit longer. He was weak.
3. This truly is what WoW does to people. It has advanced from slowly stealing people's souls and money to phyically attacking them. Horrible. The plague will spread from Sweden, people. I promise you this.
I don't think the parents are at fault though. They might be, but we don't have enough information to say so. Blaming them only on the basis that he played too long isn't fair. We blame parents for being not understanding and too constricting of video game playing, and now we blame them for being too loose? They're right to let their 15 year old sit in his room and play WoW. Maybe they could have taught him to be more aware of what he's doing to his body, but that'd be hard. Maybe he'll learn from now on.
