I've been to Nepal, but I'd like to go to Tibet. It must be a wonderful place to go. I don't think there's anything there, but it would be a nice place to visit.

I had a huge advantage when I started 50 years ago - my job was secure. I didn't have to promote myself. These days there's far more pressure to make a mark, so the temptation is to make adventure television or personality shows. I hope the more didactic approach won't be lost.

I remember when we were in the World Cup in Australia and I had to win the singles against Tony Payne, best of seven legs, to win it. I was 2-0 down but ended up beating him I suffer much less than many of my colleagues. I am perfectly able to go to Australia and film within three hours of arrival.

Terrorism is an immediate problem that people are very concerned about, and I am as concerned about that as anyone else. But it isn't an either or situation.

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

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