When you play piano, your left hand and right hand are synced. Your brain basically has a clock, so that the right hand knows that 0.3 seconds after I hit this key, I need to hit that one. And the right hand knows not to hit keys that the left hand is playing, so the hands do not collide.

The toughest trail I ever ran was the Escarpment in the Catskills of New York State. This was an 18-mile race through Rip Van Winkle country, routed through boulder fields, across angular juttings of granite and along a path with an unrelenting barrage of roots, rocks and mud, all of it hidden under slick leaves and dangling nettles.
