I fed my yak on my spare Cadbury chocolate 21,0000ft up Everest. It was a blonde, very sweet female yak. I made it my pet after that.

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!
