This is nothing new..They went from a TV  Couch potatoes to the Internet..They are all ready overweight even before they set foot in to the Internet world..These researcher are just looking for more tax payer money to tell us something we all ready know..Isn't it these same researcher tells us that the United State is FAT?

All you need to do is Google , America is Fat and it will tell you why..And it is not the internet that makes them fat..And besides America is not Fat there just pleasently Plump..Tee hee..:)

hey i might play alot of video games, but i socialize online and outside of my house. i cant really say much since i dont really know many gamers over 30. i take gaming as a hobby and no1 can tell me 2 stop.

Regarding low extroversion, yes, it can be the other way around.  People with social anxiety, for example, may feel more comfortable in a 'safe' environment such as MMOs, where one is free to log out any time if needed.  It is much harder to 'log out' in real life situations and log back in when feeling better.  o_o

For any number of reasons (agoraphobia, depression, physical health reasons including but not limited to obesity) it can be difficult to leave one's home, and effortless to log on, where there is a waiting community at all hours of the night, where people can find support of kind individuals. 

Friendships grown online can even be an inspiration to real life...  inspriation to work at bettering oneself, to eat more healthy and be more active... inspiration to try again being social in real life, since finding it so easy online... to find something worth living for when one thought life was hopeless. 

I think that they are fat and lazy is one reason why they spend more time on games, not the other way around.  If games didn't exist, they'd be watching TV.  If TV didn't exist, they'd be reading books.  If books didn't exist, they'd be sleeping.  You can't blame anything for their being fat and lazy except for themselves!  They aren't going to suddenly get up and start exercising if games weren't there.  Especially if they're talking about older people, they don't have the same energy and drive.  Geez they work all day and want to play games a little when they get home, leave them alone stupid studies!
