We live in a beauty-obsessed age and success sometimes appears to hinge solely on the presentation of an image that is acceptable to the press.

The negative about acting is that you have to spend a great deal of time away from your friends and loved ones, but it's not like working a 9-5 job and only having two or three weeks off a year. I may not have seen my girlfriend for two or three months, but then we can spend two or three months together solidly.

I want to be challenged, I want to keep challenging myself - whether or not it's changing yourself physically or just pushing yourself to a certain extreme. I get bored quite easily so I like to keep my mind entertained by challenging myself.

If you don't practice for three days, everyone will notice." It's something you have to really maintain. So unfortunately, I don't play it that often but I may take it up again. If you don't play for a while, you just can't hit the notes. It's like going to the gym. If you go and do weights, you can lift x amount of weight and if you don't go for ages, you've gotta start again and start from the beginning. So it's a bit like that. It's just a muscle.

I live alone so I always just eat out. When I'm in another relationship, then maybe we'll start cooking together.

Have you seen Cowspiracy? It takes a lot more land to feed a meat eater than to feed a vegan or a vegetarian. It's something I'd love to get into but it's very hard to persuade people to stop things they've been doing for a long time. So maybe it needs to start with the next generation. Everyone needs to raise their children with a bit more responsibility.

I live for challenges. In my career, all I want to do is try to challenge myself and have a varied career.
