In fighting, in evolution, in life, efficiency is the key.

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.

The real test is this one: When you're alone in a room, when you're in a private place and nobody else can see you, what do you choose to do? Eat well, or eat poorly? Exercise, or watch television? Practice something, or do nothing? The best version of the truth appears to you and you alone, when nobody else can see. This is the test of discipline, and it's what makes the difference in your life. It's what regulates your own system and guides it. The individual alone comprehends it.

If you want to be a proud person, then you want to avenge your loss. For me it was [Josean] Serra and [Joe] Hughes, and for Michael Bisping, Henderson is one of his losses - one of his most painful losses. So I understand why he wants to avenge it. As an athlete I understand.

If you look good, you feel good, and if you feel good, you do good.

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.

For me, personally, when I'm afraid of something - when you're afraid of something, normally you try to go away, you try to avoid it. Instead of avoiding it, to overcome your fear, I believe you need to embrace it.
