I think a major element of jetlag is psychological. Nobody ever tells me what time it is at home.

In the West, that's what's happening. The birth rate has been dropping steadily and still is. But there is still a vast amount of the world where that's not the case. And that is where the big population growth is taking place.

I'm not over-fond of animals. I am merely astounded by them.

I don't like rats, but there's not much else I don't like. The problem with rats is they have no fear of human beings, they're loaded with foul diseases, they would run the place given half the chance, and I've had them leap out of a lavatory while I've been sitting on it.

The World is full of wonders, but they become more Wonderful, not less Wonderful when Science looks at them.

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

I'm against this huge globalisation on the basis of economic advantage.
