Environmental scientists in Canada said it was impossible for me to get to the Pole in 2004... I said 'no,' it's still OK, and I can still get there, and I did.

When I'm skiing, I listen to electronic music. It's repetitive and let's me get into a groove and crank out the miles.

The strongest comments are from the Chinese scientists. This is not at all surprising. . . . Chinese protests against high-profile visits of the Dalai Lama are routine wherever he travels.

What's the nastiest injury I've sustained? Just a frostbitten toe... but thankfully it's still intact.

They can put me in a jungle. Still, I can create.

For me, it is OK as long as I can breathe, as long as my heart is pumping, as long as I can express myself.
