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 am not a Hispanic candidate. I am an American candidate who happens to be of Hispanic heritage, who understands the culture, who has worked the border and has a unique understanding of those issues. But rest assured my job is to represent all Americans as a U.S. senator.

I've had opportunities before to run for office - the Republicans recruited me when I was surgeon general, to run for Congress, to run against Gov. Napolitano. But I didn't feel it was my calling... I felt, 'Well, I'm flattered, but I really would rather stay and be the doctor of the nation and stay as surgeon general.'

I grew up in Harlem. My grandmother was one of the best cooks around, but the first thing she did on Sunday mornings when she started cooking a daylong meal was to take a big block of lard from the back of the refrigerator and throw it into the pan. I know how Hispanics buy their food, and it is not always nutritious.

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

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.

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.
