I definitely agree about the future of youth football being flag. There's just more and more evidence that the youth brain is particularly susceptible to the injury - thin necks, big heads. They're not as coordinated; they're not as skillful. For many reasons, I think the wave of the future is flag football for youth.

I was born with football - my brothers, my dad. I played football when I was a kid. I mean, you know, it was part of life. It's a part of growing up. It's - you know, it's a way of life.

My greatest hope is that we learn how trauma induces neurodegeneration in susceptible individuals.

My son was a goalkeeper in soccer, and he luckily never had much head trauma. He never had any concussions or anything. I really wanted him to play football, but now I'm thankful he didn't.

I started when I was 8 years old, which is obviously nowadays pretty late, but I guess in my generation it was all right. I had plenty of other interests and I didn't do only tennis.

Just think about the game. Think about playing great, having a great time. Helping my team win.

I grew up in a very 'Friday Night Lights,' sports-focused town. I did not play the sports. I was never bullied physically, but I was called names. I was also an overweight kid. I knew what it's like to feel like the other, to feel written off for things that were not in my control - my appearance, my interests.

I think, growing up, I was seen as the perfect power forward. For a long time, I thought maybe I was supposed to be a basketball player.
