I don't see why it should be remarkable that you can acquire a reputation for fairness and decency. Those are qualities shared by so many people. And the great majority of people I meet are decent people, just trying to navigate their way through the world without causing too much trouble.
I wanted to be an explorer, but gradually found the world had been explored and that there was nowhere left, really. Once they climbed Everest in 1953, when I was 10 years old, I thought, 'Well, that's pretty much it now.' But the idea of travelling and exploring and adventure was very strong.
There are people who travel because they want to push themselves to physical limits, people who walk across deserts or cycle across the Antarctic - like Ranulph Fiennes, who just does it because it's there. And then there are people like me, who are just genuinely curious about the world.
If you had a successful TV show, people wanted to see you live. Promoters had had practice with pop groups, and 'Python' achieved a similar status. We also had lots of rock star fans - George Harrison, Pink Floyd, Robert Plant. Promoters saw that and liked it.
When I'm travelling, I always take my little notebook and scribble things down as I watch them; I'm very much geared to everything that's happening. Whereas, the diary I keep is just about a record of a day I've spent. When I'm filming, I'm looking quite intensely at everything I see and trying to get my own eye on what we're going through.
People look for patterns in everything. It's what keeps us sane, I suppose. I struggle to see any patterns in my life. I think I can understand depression a bit because of my sister. My own feelings of... I'm aware that, if you feel down, it can be strangely unrelated to circumstances around you. That's just the way life is.
I know that we shall meet problems along the way, but I'd far rather see for myself what's going on in the world outside, than rely on newspapers, television, politicians and religious leaders to tell me what I should be thinking.
I've never had a particular skill. I can't cook, dance, play an instrument, speak a foreign language. This used to worry me. I'd think, when I'm grown up, at 18, then I made it 21, it will be clear what role I should have in life. It never happened. I never signed on the dotted line as the sort of adult my father wanted.
There is nothing better than playing a scene with John Cleese or Maggie Smith. It's electric. But I don't think I'm the sort of person who needs to have an outer ego in order to produce something. I realised that through the travel programmes.
Hollywood was possible for a while! Why didn't I go along with it? Well, the other things that were pulling me back were more important. Being at home, being in the same marriage, these things enabled me to go off and travel in the first place.
Something about John Cleese was always very unsettled, I felt. There was always something else he wanted to do. He seemed constantly driven by this sense that there was a nirvana somewhere; some unique place where mind, body and soul would be utterly satisfied.
I've been lucky to have made a number of travel programmes with the BBC, the object being to see places off the beaten track. As a result, I've often had a guide who's been able to show me things that you wouldn't see with a tour group.
You don't ask people about the immigration policies of the U.K. or their country's agricultural policy. Instead, you talk to them about the meal they're eating or their family, and from that you get the sense of another human being, someone we can all relate to.
