I've always been blessed, or cursed, some might say, with an insatiable curiosity, a desire to find something out about a people and a place. That's where it all begins.

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.

I've been lucky enough to stand on both poles, but the place that seemed the remotest to me was Butugychag, a former gulag in Siberia. It is completely cut off from the rest of the world.

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.
