You can't have one take precedence; it has to be both. The approach can be independent, and some of the approaches to get physical activity are different from some of the approaches for nutrition, but it's pretty tough to pick and choose which one. They're so interrelated, and I think that's what the evidence has shown us. That gets into the interventions you do. You can't pick one particular intervention or magic bullet; you've got to do a myriad of interventions.
I want to follow up on Mary's comment earlier. My wish list--I think this is what you're getting at--is going to take a long time. This is going to take a large investment of a long period of time. We're all in this for the long haul because what this is reflecting is the fabric of our society. Little interventions aren't going to do the trick. It's going to take societal change; it's going to take differences in terms of how we build, how we structure, how we school, rewards and punishments. Your example is quite interesting. Daily physical activity used to be in schools and it's gone. Now it's starting to come back, and we're realizing we've gone backwards there. But that daily physical activity can't be isolated without having some of the junk food taken out of schools, etc. So it really has to be both. I'm sorry, I can't answer one or the other.
Mary is dying to say something.
