The statistics are alarming. Two-thirds of the adults in the U.S. are overweight and one-half of that group is considered obese. Every year those numbers get bigger. But it's not just adults who are tipping the scales, kids are gaining weight, too. One-third of all school-age children are overweight and when bad habits start early, they're hard to break. A nursing group from Mayo Clinic wants to change that. They're working with public schools, nursing students and parents to help kids get and stay healthier.
