Avatar as Workout Buddy

Obesity is a major health problem in the United States, and it is a particularly difficult problem to treat. And once dieters have lost weight, it is particularly difficult to keep weight off. Some turn to support groups.

But could motivation to get fit and maintain a healthy weight come from an avatar in the online site Second Life? It can, believes one researcher. NPR reports.

Questions...

•How is the online version of you (your avatar) the same as the physical you? How is it different?

•Can an avatar be a role model?

•Why do you think the Second Life weight loss plan works?

•Does vanity exist online? Does it matter what you avatar looks like?

•How else can the Internet help with your health?
