Exercise makes us better thinkers
Another explanation for why working up a sweat enhances our mental capacity is that the hippocampus, a part of the brain critical for learning and memory, is highly active during exercise. When the neurons in this structure rev up, research shows that our cognitive function improves. For instance, studies in mice have revealed that running enhances spatial learning. Other recent work indicates that aerobic exercise can actually reverse hippocampal shrinkage, which occurs naturally with age, and consequently boost memory in older adults. Yet another study found that students who exercise perform better on tests than their less athletic peers.
Everyone has a plan until they get punched in the face.
That was the real secret of the Tarahumara (ed. group of indigenous people of the Americas living in the state of Chihuahua in Mexico who are renowned for their long-distance running ability): they'd never forgotten what it felt like to love running. They remembered that running was mankind's first fine art, our original act of inspired creation. Way before we were scratching pictures on caves or beating rhythms on hollow trees, we were perfecting the art of combining our breath and mind and muscles into fluid self-propulsion over wild terrain. And when our ancestors finally did make their first cave paintings, what were the first designs? A downward slash, lightning bolts through the bottom and middle--behold, the Running Man.
Distance running was revered because it was indispensable; it was the way we survived and thrived and spread across the planet. You ran to eat and to avoid being eaten; you ran to find a mate and impress her, and with her you ran off to start a new life together. You had to love running, or you wouldn't live to love anything else. And like everyhing else we ove--everything we sentimentally call our 'passions' and 'desires' it's really an encoded ancestral necessity. We were born to run; we were born because we run. We're all Running People, as the Tarahumara have always known.
As [the martial art student] studies various things and is taught the diverse ways of how to take a stance, the manner of grasping his sword and where to put his mind, his mind stops in many places. Now if he wants to strike at an opponent, he is extraordinarily discomforted. Later, as days pass and time piles up, in accordance with his practice, neither the postures of his body nor the ways of grasping the sword are weighed in his mind. His mind simply becomes as it was in the beginning when he knew nothing and had yet to be taught anything at all. In this one sees the sense of the beginning being the same as the end, as when one counts from one to ten, and the first and last numbers become adjacent.
The mind must always be in the state of "flowing," for when it stops anywhere that means the flow is interrupted and it is this interruption that is injurious to the well-being of the mind. In the case of the swordsman, it means death. When the swordsman stands against his opponent, he is not to think of the opponent, nor of himself, nor of his enemy's sword movements. He just stands there with his sword which, forgetful of all technique, is ready only to follow the dictates of the subconscious. The man has effaced himself as the wielder of the sword. When he strikes, it is not the man but the sword in the hand of the man's subconscious that strikes.
[...] true knowledge [...] is experiential. How do we explain the taste of sugar? Verbal descriptions do not give us the sensation. To know the taste, one must experience it. The philosophy of the arts is not meant to be mused over and intellectualized; it is meant to be experienced. Thus, inevitably, words will convey only part of the meaning.
