"This is something I am very enthusiastic about," said Dr. Bill Crounse, a family physician and now Microsoft's senior director or worldwide health. "Since I started as a physician in the early 1980s, we have seen about a tripling of the number of kids overweight or of childhood obesity ... and it has to do with inactivity. I reflect back to when I was growing up and kids were always running around. This is a way of getting kids and their families more motivated to get active."
"As a physician, we know being overweight and obesity is associated with a lot of chronic diseases that are major causes of death in the United States," Crounse said.
