For me there is no reason why to go up in weight class, because when you go up in weight class you have to fight bigger guys - then you have to train against bigger guys. The guys are not better, they're heavier, but it means you have more chance to get hurt.

People have mistaken my break, I took a break from competition, it was because of mental problems, and because I was not agreeing with Performance Enhancing Drugs. I put the things on pause for a while, but I didn't retire.

My mentality is like a Samurai: They used to every day work on their technique to make themselves almost perfect. Because perfection is impossible, but every day, you get closer to perfection.

The beach in Tel-Aviv I went to, it even looks and feels a little bit like Rio de Janeiro. Some other places are very European and I just like it. I thought it would be fun but it's a lot better than that. It's a lot more relaxed and a lot of fun, and I feel very secure, and I would tell my friends they should come here when they plan a vacation. Not only the history.

Fighting is about knowledge, knowledge is a very important part of it.
