Researchers polled 7,000 players of online role-playing game EverQuest II about their physical and mental health and found out that the average adult gamer has a lower body mass index than the average American:
Researchers at the University of Southern California in Los Angeles, the Palo Alto Research Center, also in California, and the University of Delaware in Newark, quizzed 7000 players of the role-playing game EverQuest II about their physical and mental health. Participants were offered a specially created virtual weapon as an incentive - the "Greatstaff of the Sun Serpent". The researchers then combined the survey responses with statistics about players' online activities and playing habits.
The results suggest that adult gamers have an average body mass index of 25.2, compared to the overall American average of 28. The average gamer also engages in vigorous exercise once or twice a week, which the researchers say is more than most Americans. The reasons for this are not obvious, although the team suggest it may be because more educated, wealthier people are attracted to computer games, and these people also tend to take better care of their health.
However, while they were physically fitter their menthal health was below average. More info at NewScientist.
