Driving a motorcycle is like flying. All your senses are alive. When I ride through Beverly Hills in the early morning, and all the sprinklers have turned off, the scents that wash over me are just heavenly. Being House is like flying, too. You're free of the gravity of what people think.
You live overseas, you see these exotic places and you want to know about them. But, weirdly, it also made me homesick for all these very prosaic places in America.
I think what a life in science really teaches you is the vastness of our ignorance.
