I hope I succeed in demonstrating that you may equally find compelling and significant narratives - stories that alter or add to our understanding of history - in unprepossessing places: a Victorian sewer system; a Cold War bunker; derelict hospitals.

I was brought up in a house where I was so aware of a life that had been broken by politics and conflict.

I don't know why, but I think the eating of food is hugely enhanced when you do it on a train. Even a simple steak and chips, when the world is rushing past outside, can take you to heaven.

What is it about trains that makes food taste so good? Some of my happiest memories are of prolonged lunches between St. Moritz and Zurich, Bordeaux and Paris, and even between Coimbra and Salamanca.

I travel all the time, and I have two small children.

Older men are wiser and that is much cooler to me. I've never been one for going out clubbing or getting off my head, so I always gravitated to men who were similar. They just tended to be older. I think you have more of an adventure with an older man. And a happier journey.

All you need is the plan, the road map, and the courage to press on to your destination.

Life is an adventure, it's not a package tour.
