I've never thought about the end of my career. I've had this growing motto in my life to live day to day - and when you live day to day, it's hard to talk years.

I've always been fascinated by the military, the discipline they have and the sacrifices they make to defend the country. It's something I've always been interested in.

I don't look at football as a violent, barbaric sport. It's a very spiritual sport, especially for someone facing the challenges during a game: the fear of failure, the fear of getting too big an ego, of making a mistake and everybody criticizing you.

If you don't eat right as an athlete, you'll get tired and won't be as sharp. It's simple to drink sodas and sports drinks, but water is the most essential drink to put in your body.

A big hit is all part of the game. If you want to make a lot of big hits, you forget about the one you just made and move onto the next one.

Fighters are raised into MMA. It's more about what's internal, not what's God given. When you have a great fighter like Rickson Gracie or Fedor Emelianenko-they're greater than the others because they have an internal spiritual being that separates them from the rest in their craft. They have the warrior spirit.
