The household I grew up in... was rather like an Ovaltine advert. There was a huge fire, a kettle on the fire, the oven with the bread being baked every day, and there was the radio; it was very magical to hear all these wonderful programmes.

My brother Alan - who was seven years younger than me - died from leukemia when he was 52. He never knew a day's good health - I wish I could have given him some of my good health. But he was always so cheerful and sweet.

I've completed half of my space training at Space City in Moscow. I love adventure, and I've been training in a centrifuge and MiG Fighter with a view to going into space and being a spokesman for space exploration!

My parents taught me honesty, truth, compassion, kindness and how to care for people. Also, they encouraged me to take risks, to boldly go. They taught me that the greatest danger in life is not taking the adventure.

I'll never retire. The new millennium is the age of adventure as far as I am concerned. I'm going up a volcano and off into space.

You can't call it an adventure unless it's tinged with danger. The greatest danger in life, though, is not taking the adventure at all. To have the objective of a life of ease is death. I think we've all got to go after our own Everest.

The greatest danger in life is not taking chances. There are so many negative people wanting to grind you down, but you can't let them. If people say you are mad, you know you're on the right track.
