I'm probably not going to be popular with the fighters with this one, but my biggest problem is guys playing it safe. I understand it from a coach's standpoint and a manager's standpoint. I understand why you'd want to play it safe and want to win the fight, win every fight. I get it.

That's one of the reasons I retired. To stick around, the way I was fighting, I would have to start playing it safe. I went out on my shield. That's the way I liked it. I fought that way my whole career. I don't want to bore people my last three or four fights.

I thought I could beat anyone in the world.

It's one of those things: I'm never gonna get over not fighting, I don't think, but I'm content with my decision to retire.

Everyone is on a fair playing field. It's safer for athletes, it's safer for the fighters - it's just a safer thing for fighters. So I think the USADA thing is good.

Supplements have always been a really big part of my training regimen.

I like aggressive fighters who will come after me.

A lot of people are blowing Shogun's fight with Mark Coleman out of proportion. He was coming off an injury, and he gassed early on in his first fight back.

With the fights I have lost, I always want another shot and think that I can beat them.

I'm competitive at everything.

I don't like being bad at anything.

'Dancing with the Stars' was hard work. It was interesting and fun, too, but it was hard work.

It's a very complex sport, so judging is going to be very complex, too. And not everyone is going to agree all the time on who wins a fight.

My whole life, I've been training for something, whether it be baseball or football or wrestling or martial arts.

Conor McGregor has a big mouth. But I do love the way he fights.

Totally different challenges, but being a dad and fighting both wear you out.

I like Glover Teixeira; he's a former training partner.

The worst thing is losing because you got tired, because you didn't work hard enough in training. Ugh, that's the worst.

If you watch fights cage-side, sometimes different punches look better than others. It's like camera angles. Sometimes some punches look a lot better than they were, and sometimes a solid punch doesn't look good. So it just depends on your angle.

I used to be able to pick out the UFC fans when I was in the airport. Now, it could be anybody.

The most excited you'll ever see me is after knocking a guy out.

I never expected it, but I've gotten paid a lot to do what I love. There are no complaints.

When it comes to damage, boxing will cause more damage than MMA ever will.

We run on the beach some days, and others, we run hills behind the gym. We also do several hours of grappling each week as mixed with some intense cardio in the ring.
