If I can bicycle, I bicycle.

All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.

If I can make programmes when I'm 95, that would be fine. But I would think I'll have had enough by then.

To suggest that God specifically created a worm to torture small African children is blasphemy as far as I can see. The Archbishop of Canterbury doesn't believe that.

I can mention many moments that were unforgettable and revelatory. But the most single revelatory three minutes was the first time I put on scuba gear and dived on a coral reef. It's just the unbelievable fact that you can move in three dimensions.

I believe the Abominable Snowman may be real. I think there may be something in that.
