I am very honored and excited to be part of UFC 100, it's going to be the hardest challenge of my career so far and it's going to be pretty tough, I can't wait.

I've started late, I was 19 years old. I've trained with Victor Zilberman - he's a Russian-Jewish from Moldova. His son David who is coaching me represented Canada in the Olympic games. There were a lot of very good wrestlers there and they took me underneath their wing when I was young.

Nick Diaz is a champion so he's got the spirit that comes with it. So he's not going to give up mentally. You see a lot of guys give up mentally and that's why they get knocked out or submitted. They give up mentally before they lose.

Kyokoshin I've done most, but I competed in Sports Karate also, that's my style that I come from, and mixed with the wrestling that's how I got the takedowns.

I don't want to be an exception, because I was very outspoken about Performance Enhancing Drugs. It would be bad for my reputation if I would have an exemption [for doping test] - I don't want to have a free pass, I want to be like everybody else.

I don't want things that I regret in life, and things that I have not done - and I don't want to at 80 years wake up, and tell myself: 'Oh I was on top of my shape and skills and I didn't do it.'
