“Walking is the best way to go more slowly than any other method that has ever been found. To walk, you need to start with two legs. The rest is optional. If you want to go faster, then don’t walk, do something else: drive, slide or fly. Don’t walk. And when you are walking, there is only one sort of performance that counts: the brilliance of the sky, the splendour of the landscape. Walking is not a sport.”
