We've got to do something about it. It's systemic. It's epidemic. It's a disaster. And we've got to intervene. It's part of our school system, with the school lunches, as we showed. It's the fast-food businesses and those kinds of organizations coming in and sprinkling their fish food around the schools and trying to poison our children. That may sound harsh to say, but that's just what I believe. When there's cookies and soda and all sorts of stuff that's cheap and accessible to these kids, they're going to eat it. It doesn't have to be this way, but we have to hold everybody to task on this. There's no reason we shouldn't have physical education in every school system for every child."
