Many of the negative aspects of video games are tied to excessive play. In Korea, a 28-year-old man died from exhaustion after marathon sessions of an online game known as a MMORPG (massively multiplayer online role-playing game). Excessive playing leaves less time for academics, social development, and physical activity. When kids become obsessed with "passing the next stage" and "getting to the next level," much like an addict, they may begin to lose their interest and desire for anything else. One public health consequence is that children and teens are much less physically active than in prior generations and we face an epidemic of overweight and obese children.
