Despite having seen a fair amount of the world, I still love travelling - I just have an insatiable curiosity and like looking out of a window.

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.

Please don't ask which I enjoy more - acting or hosting - because I love them equally.

I will die, but not retire.

People say the most stupid things on the spur of the moment that they then have to retract.

Once the travel bug bites, there is no known antidote.

Once the travel bug bites there is no known antidote, and I know that I shall be happily infected until the end of my life
