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.

My main goal for taking up acting as a profession was to show that sport or MMA teaches you life skills that can be applied to any profession in the world.

My role at the USTA allows me to fulfill my ambition to open up opportunities for people to play tennis that may not otherwise have a chance or an outlet to play.

Don't let anyone turn you into a slave. You're a slave if you let the media tell you that sports and entertainment are more important than developing your brain.

Unfortunately, wrestling in India doesn't have the same appeal for the youth that cricket and football do. For this reason, I want to also begin a series of wrestling academies across the country.
