I don't approve of sunbathing, and it's bad for you.

Nature isn't positive in that way. It doesn't aim itself at you. It's not being unkind to you.

London has fine museums, the British Library is one of the greatest library institutions in the world... It's got everything you want, really.

The more you go on, the less you need people standing between you and the animal and the camera waving their arms about.

You know, it is a terrible thing to appear on television, because people think that you actually know what you're talking about.
