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'm a fully trained cosmonaut and have completed 800 hours training, which has made me the No. 1 civilian reserve ready to visit the International Space Station. I am determined to go up, and I want to explore the Moon, Mars and beyond!

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.
