Perhaps you could say that mountaineers are driven by ego or our competitiveness, but there's a lot more to it than that. Whether it's a huge face in the Himalaya or some crag in the woods behind your house, exploration offers us a unique perspective on the world that you can't really find anywhere else.

Specifically choose not to take a GPS. Just create a challenge. You can climb Everest or walk across Antarctica with minimal gear and still have that sense of adventure. But in terms of exploration, Google Earth has this world mapped down to the square foot.

Climbing, as my grandmother said, it's a pretty frivolous thing. She always wondered when I was going to get a real job. But climbing is a real job for me now, and I enjoy it. It's a gift that I'm able to do it, share adventure and motivation with people.

It's our human nature to explore. Tens of thousands of years ago, our species walked out of Africa, traveling far and wide across the entire planet, from the Arctic to the tip of Tierra Del Fuego, making us the most geographically diversified species on Earth.

I wasn't a big fan of social anthropology. And, luckily, that created room for me to work in visual arts because I sort of ignored my requirements. I think I was attracted to social anthropology because I liked to travel and was always interested in far-off places.

I've been travelling around the U.K., actually getting to see places. I'm so lucky that I am able to travel with work, but you don't often get to experience them properly.

I always wanted to do action-adventure, and science fiction genres were always something that were of great interest to me.

Often in my game as an actor, someone else pays for your travel and there's nothing like being able to lie flat on a flight home from L.A.
