Life and love inspire me. I think reinventing yourself is vital to your survival as an artist and a human being. I know it’s cliché to say about me at this point, but it’s true. My curiosity definitely is the driving force in my life and career. When you stop learning, engaging and growing, you’re dead.

We've made so many advances in other areas - civil rights, gay rights - but ageism is still an area that's taboo and not talked about and dealt with.

I was working with Toby Gad, who spent a lot of time in India. There's a sitar [in "Body Shop"] and the song has a very Indian flavor to it. I liked the idea of the body of a car as a kind of sexual metaphor - What you do to a car, what you do in a car - drive. So, lots of innuendos, and lots of fun.

We're very privileged as Americans - it's easy to forget about the rest of the world and to think that your problems are the most important problems. Even poor people in America live better than poor people most everywhere else.

In this business, my business, I get to meet all kinds of incredible people, fascinating people, glamorous people and sexy people and highly intellectual people. And you meet them and you go 'interesting, interesting, interesting'. They're interesting, but not very many people stop you in your tracks.

I don't take drugs. I never did. All the feelings that drugs are supposed to produce in you - confidence or energy - I can produce naturally.
