I like learning new stuff, and continuing to educate myself as best I can.

If I had a choice as to my perfect career, I would make a couple of films a year and then concentrate on natural history.

When I was at college, I worked in a department store called Brit Home Stores, which is a pretty lackluster department store, selling clothes for middle-aged women. My job was to walk the floor and find anything that was damaged, take it to the store room and log it.

My brother's a teacher in Costa Rica and actually does a more important and significant job than I will ever do.

Almost everything worthwhile carries with it some sort of risk, whether it's starting a new business, whether it's leaving home, whether it's getting married, or whether it's flying in space.

Romance and girls I don't talk about anymore: it's off limits. I just want to keep it private.

I think what makes our marriage work amid all the glare is that my husband is my best friend. He inspires everything in my life and enables me to do the best that I can. I want to hang out with him more than anyone.

It's a classic love story: me and my hair. I have loved my hair. I have betrayed my hair. My hair and I have gone through this long, gut-wrenching relationship.
