My view of chronic disease prevention of fighting epidemic obesity and diabetes, of turning the tide, is that it is the job of professionals to pave the way and to cultivate the will; to stir people up so that they understand the stakes, so that they recognize that adult onset diabetes stalking children is a clear and omnipresent danger. The wolves are at the door. You must defend hearth and home. And here are the means to do it: we must provide programs, policies, tools and resources so that everybody can do the job.

What we need to do now is recognize that it is the sum total of human ingenuity that is responsible for the epidemics of chronic disease. Throughout most of human history, calories were scarce and hard to get, and physical activity unavoidable. Calories are now abundant, and physical activity is hard to get. We took an unstable, uncertain food supply and fixed it. What now passes as exercise and requires specialized footwear used to be called "survival." You had to do it. Now you never have to do it. We solved it too well. Now we don't need our muscles for anything.

We have literature indicating that overwhelmingly, health is influenced by a very short list of modifiable behaviors topped by three: tobacco use, physical activity and dietary pattern. You could modify those three things; you can change people's fate. I wanted to change those. Smoking cessation, important but relatively simple - a lot of people are working on that. Physical activity: important to me, important to health but also relatively simple. I like nutrition. It's complicated; you really need to learn a lot of stuff to be an expert there.

We don't control everything. There are genetic influences. There are environmental exposures we don't control. I cannot guarantee anyone I counsel that by following what I hope is the good advice I offer them, they will live long and prosper. That's what I'm hoping for but I can't guarantee that. What I can tell them is this: "Look, I can help you firmly grip the wheel, and you can steer the ship. You're never going to control the winds and you're never going to control the seas. But if you sail well you can get through just about anything."

We have a society that monumentally conspires against the pursuit of health. We have wave after wave of labor-saving technology that says don't ever use your muscles for anything, along with messages that you should be more physically active. We have, every year, the introduction of hundreds, if not thousands, of new highly processed foods, the majority of which glow in the dark. At the same time we're telling people: eat foods closer to nature. We have schools where we teach children to sit still all day long so they can become adults we can't get off couches with crowbars.

We are creatures. We have a link with a native habitat just like every other species. Throughout most of human history, physical activity was unavoidable, calories were scarce and hard to get. In the modern era, calories are unavoidable, physical activity is scare and hard to get. The traits that allowed our ancestors to survive, and let's face it, the survival of our ancestors is the reason that we're here because the people who don't survive and make very crummy ancestors, are our traits. But they're very much at odds with the modern environment.

Color, rather than shape, is more closely related to emotion.
