Duane Desiderio, a vice president at the National Association of Home Builders, quoted by the Boston Globe: "Obesity is more a problem of nutrition than where you live. There are plenty of suburban developments with miles and miles of hiking and jogging trails. And people in high-density [developments] could still eat potato chips.'' Desiderio misses the point. Most folks don't have the time to get out on those hiking and jogging trails. But if they could walk or bike to work one day a week, it would make a huge difference.
