My muscles are the type that need a long time to warm up…. And I feel that this type of muscle is connected to the way my mind works. What I mean is, a person’s mind is controlled by his body, right? Or is it the opposite—the way your mind works influences the structure of the body? Or do the body and the mind closely influence each other and act on each other?

—Haruki Murakami, What I Talk About When I Talk About Running
