Depression is a physical illness.

I’m always happy-go-lucky, and people look at me and find it shocking that I could be depressed.

Imagine yourself sitting on top of a great thoroughbred horse. You sit up there and you just feel that power. That's what it was like playing quarterback on that team [the Pittsburgh Steelers]. It was a great ride.

I'm taking memory power boost tablets to help me every day and doing the puzzles to help me stay focused.

When I played for the Steelers and I got my bell rung, I'd take smelling salts and go right back out there.

You've got to stand up and do your own battles. My daddy taught me that a long time ago, that you fight your own battles. The only way to shut everybody up is to win.

When you've got something to prove, there's nothing greater than a challenge.
