I loved my time growing up in Northern Ireland doing youth drama, that is where it all began for me.

When I was growing up, Belfast City Hall was surrounded by security, and we had no access to it. But now, people come in and out of it all the time. On a nice day, office workers and students sit on the lawn outside and have lunch. It's great to see how Northern Ireland has changed. To be part of that is fantastic.

I get an awful lot of people coming up and saying they went to school with me. There must have been 80,000 pupils at that school!

In my life, I have made the occasional catastrophic choice, and it's just a case of moving on and learning from it.

I like to make my fights exciting and different. Everybody in UFC can fight; we're capable of kickboxing, wrestling, but I like to stand out. That's what I really pride myself on. What can I do to stand out from the other people in my sport.

As a physician, I'm somewhat an advocate of patients. How come, before Mike Webster, no NFL player was told or knew that there was an intrinsic risk of brain damage from playing football?

Football is very changeable, particularly at international level when you're not working together every day.

I was an athlete, but I hung out with the band guys. I was adaptable.
