“ It’s a moving belt. About a quarter of a mile long ... You just stand there and it carries you all the way to the baggage-claim area. But if you want, you don’t have to just stand there. You can walk on it. Or run. And it seems like you’re just doing your normal walk or your normal jog or your normal run or your normal all-out sprint—whatever—because your body forgets that what you’re really doing is topping the speed the walkway’s already making. That’s why they have those signs that say SLOW DOWN, MOVING RAMPWAY near the end. When I met you I felt as if I’d run right off the end of that thing onto a floor that didn’t move anymore. There I was, my body nine miles ahead of my feet. You can’t keep your balance. ”
