I made my debut for South Africa at the age of 21. It was a very special day in my life being able to represent my country, but unfortunately it ended after seven minutes when I tore a ligament in my knee. It wasn't a great start to my international career, although I returned after nine months of rehabilitation.

The most challenging part of rugby, I would say, without a shadow of a doubt, is the injuries -- and I've had a few in my career. While you are going through it you don't always see the light at the end of the tunnel, but I've grown a lot as a person and become closer to my family and friends.

A lot of the time you blame everyone for what happened to you but you just need to take it on the chin and work harder to get back to the top.

I was pretty lucky when I grew up that I went to quite a good rugby school . I think the coaches I had were very good and they played a big part in my development as a rugby player.

I think the 1995 World Cup final was probably one of the best days in South African history (it was the first major sporting event to take place in South Africa after the end of apartheid and South Africa won). It has got such a big part to play in uniting the nation and was definitely the best day that we've had as a rainbow nation since 1992 (when white South Africans voted to end apartheid).

I grew up in Paarl (a small town in South Africa's Western Cape province) and I remember running in the streets with the national flag and seeing everyone outside and (car horns) hooting. It was a fantastic day. It showed what sport can do to unify a nation -- and definitely what rugby can do in South Africa.

When South Africa won the World Cup in 2007 , it was a bit different for me because I got injured in the first game -- and ruptured my bicep. Even though I was part of the team and got my gold medal for winning, it was a bit of an empty feeling. I never really felt that I deserved it, but that was a great day, (especially) when the team arrived back in South Africa to see the faces of millions of South Africans. I think that's the pleasure you get from playing rugby -- to see the difference that you can make in the lives of others.

I met Nelson Mandela and took a photo with him and the William Webb Ellis Cup (awarded to the winner of the Rugby World Cup) when we won it in 2007. That was very special. He is an unbelievable person and I was very fortunate to meet him. He has a great love of rugby. It was funny, a couple of times he came to our games. Let's say of the five or six times he came, we played unbelievably well and won all of those games. He's just got that aura to get the best out of any person.

My role on the pitch is taking the decisions, making sure I handle the referee in a good way and making sure I get the message across to the team. When I feel some of the calls are going against us my role is to be able to have a talk to the referee to get a feel for where we're at and what we need to change -- maybe put a little bit more pressure on him to get the calls to go our way.

Playing under South Africa's first black coach (Peter de Villiers) was good for me. I played under him in the Under-19 team. He was a different coach, he had different methods and I think a lot of the time he was misunderstood. But I think it was great for South Africa to have him there and he did a good job.

Stirling Mortlock, It's difficult to single out one guy who is my toughest opponent, but because I've been playing for 10 years, I would say a combination of Tana Umaga Brian O'Driscoll and more recently Sonny Bill Williams and Ma'a Nonu -- it's always a great challenge playing against those guys.
