It’s impossible, without its affecting your health, to show yourself day after day contrary to what you feel, to lay yourself out for what you don’t love, to rejoice over what brings you misfortune. Our nervous system is not an empty sound, not a fiction. It’s a physical body made up of fibers. Our soul takes up room in space and sits inside us like the teeth in our mouth. It cannot be endlessly violated with impunity.
From Pasternak's "Dr. Zhivago"
