Ever since I was a kid I've always loved history. I think that kind of catapulted things, but I would say the two major factors were maybe 9/11 and the election of Barack Obama.

I get a lot of people that are thanking me for speaking out about certain issues. I get people telling me, "If you don't like it here, then there's plenty of other countries to go to," which is hilarious to me. I don't take anything personal. A lot of people are blinded by their love for this country.

I'm not going to be the guy to be 36, 37 years old still trying to hang on and play in the NFL. I'll be 33 in a couple weeks, and there's a million things I want to do with my life before my time is up, which is hopefully 40, 50 years down the line from now at least. So I'd definitely be content.

It's like, 'Wow. Yes, I had fun... but damn, was it really all worth it when I'm in a wheelchair at the age of 45 and can't play with my grandkids?'

I always hear people saying, "If I can just help one person, or if I can just stop one person from doing what I did." I don't think one person is enough. I feel you can help more than one person, help as many as you can. That's something that I would like to leave as my legacy: That I helped a lot of people and made some people make better decisions after looking at the decisions I've made in my life.

You're never going to get rid of the injuries. The injuries are going to happen as long as there's football, especially the way it's always been played. So that's something that won't go away. But I guess they're trying to do the best they can to reduce those injuries and really take guys out of harm's way as much as they can.

I think whenever you go through something of that nature, you get to see who's really on your side and who's really there for you. That happened in my case. And it really let me understand that no matter how small of a decision you make, it's going to have a subsequent action or reaction, and something that started out very innocent turned into the tragedy that it was.
