Because of my capacity for listening to strangers' tales, or the details of their lives, my patience with their food and their crotchets, my curiosity that borders on nosiness, I am told that anyone traveling with me experiences an unbelievable tedium, and this is why I choose to travel alone.

The job of the travel writer is to go far and wide, to make voluminous notes, to tell the truth.

The people I've known who've done great things of that type - you know, building hospitals, running schools - are very humble people. They give their lives to the project.

When I left Africa in 1966 it seemed to me to be a place that was developing, going in a particular direction, and I don't think that is the case now. And it's a place where people still kid themselves - you know, in a few years this will happen or that will happen. Well, it's not going to happen. It's never going to happen.

Fortunately, I'm very healthy, and my body is still intact. It hasn't aged very much, I feel like a very young 56. I exercise regularly, and when I do, I always learn new things about my body.

I have a healthy body, free of the chemicals that once controlled it.

If I wake up in the night terrified, I try to find a way to not let the fear have me. Every moment you spend in fear of cancer is a moment you've wasted enjoying life. Replace that fear - get in the moment and enjoy it.

Family is everything to me. Family and health are the two most important things to me.
