As I say, we Norwegians love our woolens, and you can buy some beautiful knitwear in Oslo. They might cost you a bit - but they will last.

When you're an established name, you know that a children's book will have a pretty good chance of getting picked up. Like Madonna. It's not that I had this great idea. Actually, in my case, it was a great idea.

I wasn't that into crime novels at all, but a friend introduced me to the work of Jim Thompson - I loved all his books.

In most sports, your brain and your body will cooperate... But in rock climbing, it is the other way around. Your brain doesn't see the point in climbing upwards. Your brain will tell you to keep as low as possible, to cling to the wall and not get any higher. You have to have your brain persuading your body to do the right movements.
