I used to be a real doctor. Now I just play one on TV.

If the childhood obesity epidemic remains unchecked, it will condemn many of our kids to shorter lives, as well as the emotional and financial burdens of poor health.

In 1967, I signed up for the Army where I earned an equivalency diploma, then went on to join the Special Forces. That was really was the turning point in my life. I became more disciplined and focused. I went overseas and was in combat, got wounded a couple of times, lost a lot of good friends but matured a great deal.

I really think the most important thing I do is to protect the dignity and the integrity of the Office of the Surgeon General.

As 17th U.S. Surgeon General, I was privileged to serve as the nation's doctor. I focused much of my time on promoting proven programs and individual steps that lead to good health.

The overarching issue, really, is our surgeon general should be able to communicate transparently and honestly with the American public on all issues.

As a father, physician and nurse, I have a special place in my heart for children, and I know the brief window of opportunity we have to teach them simple lessons that can lead to a lifetime of good health.
