The military played polo. Polo, really, started as a game to train for war.

Charity is another passion of mine and I think it's important to give back. I'm a lucky guy, I've had a great life, I have a great family. I'm very blessed that way, so I believe in giving back a lot.

In the beggining of I was getting all this feedback from people saying, "What are you doing? What is this?" But I thought to myself, "This is a great opportunity. This is a perfect bridge to help me achieve my dream and my vision of polo becoming a bigger, more visible sport." So I used the money that I was getting from modeling to buy better horses and to become a better player. So I really believed that if I could elevate my game and show that I was serious about it, then the work I was doing with Ralph Lauren would become that bridge that I was looking for to take the sport further.

I'm a really lucky guy, I have a good wardrobe of suits and things, and I have a wife that gives me a direction if I'm doing something wrong. I live a great life and I do what I love, which is wonderful.

Prince Harry is a great guy, very competitive; he's been playing polo all his life. Riding is in his blood. His grandmother loves horses, his grandfather played polo, his father played polo, his brother plays polo, so it's in his blood. He likes to play hard, we joke about it and it's great.

I also believe that using polo as a platform to give back is a very humble way to position this sport, because people sometimes look at this sport as a little bit snobby. So I love to use polo as a platform to help.

One out of four kids in Lesotho has AIDS, and the idea of the charity is to help the children first fight the stigma of living with HIV and then teach them how to live with it and survive and get an education so all these children can have a normal life. When you're changing the life of so many kids - one out of four is a big number - you change the direction of an entire nation.
