'Chicago Fire' has been a wonderful outlet for me. We're thrown into the gritty streets of Chicago working among actual first responders. They're a wonderful bunch, and the sense of community among Midwesterners is very similar to Australians.

I've met many rich kids over the years. Many are very down to earth and work hard; they come from decent parenting. Others, however, are not.

I work 14-hour days on-set, and when you go home to an empty apartment, the last thing you're going to do is cook a meal. I eat cereal, eggs, or smoothies. That's my routine.

I'm really good at not getting sunburned because I wear zinc cream.

I play the didgeridoo using circular breathing.

In terms of people who we call heroes - and I don't tend to like that term, and firefighters don't consider themselves heroes - but if you look at their job description, they are. Their job is to straight up save people.

I support firefighters.

I love politics.

'House' has opened a lot of doors for me. I've met a whole bunch of people and got a whole new bunch of contacts. I've got the golden ticket.

I did some good stuff over in the U.K., but I wasn't consistently working. For a while there, I was going, 'Do I really want to do this - should I go back to university?'
