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

I'm absolutely strict about it. When I land, I put my watch right, and I don't care what I feel like, I will go to bed at half past eleven. If that means going to bed early or late, that's what I live by. As soon as you get there, live by that time.

I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.

Before the BBC, I joined the Navy in order to travel.
