Geography is the subject which holds the key to our future

My marriage has worked because I am not around much.

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.

John Hall, my geography teacher at school inspired me to a lifelong interest in geography and a curiosity about our world which has stayed with me through my life. Geography is a living, breathing subject, constantly adapting itself to change. It is dynamic and relevant. For me geography is a great adventure with a purpose.

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.
