At one point in time or another, everyone's an outcast, and you have to deal with those sort of issues in society. Especially for teenage kids, I don't think there's anyone that's really been through childhood and not been an outcast in one way or another.

I do weights and work out different body parts on different days. I don't do cardio - I did too much in my tennis-playing days!

I think every character I play definitely has parts of me. I can't ever play someone that's completely different to me.

I try to stay away from processed foods. I eat lean meats and get as many veggies as I can on my plate, so when mum calls me on a Sunday, I can tell her I'm eating enough veggies! I love pasta, but I don't eat carbs a whole lot, and I love fruit.

I mean, the first 'Back to the Future' is kind of a perfect script, I think, in terms of handling time travel the best. It depends on your definition. To me, that means it effectively uses it in the story.

If I could time-travel, I would either go to the '70s and watch the first 'Star Wars' film the day it opened, or to 1880s London, during the Jack the Ripper era, and experience the true grossness of that time.

Many people don't know, but American Girl Scouts get to travel the world, and that's a very good thing, as the more we can expose our young people to other cultures, the better off we'll be in this increasingly globalized environment.

I hope there will be continued U.K. investment in human spaceflight to enable Britain to benefit from space travel in the longer term and that many more Britons - women and men - will travel into space.
