“Our bodies align with these rhythms of life in our footsteps (slow tiptoe or urgent stomp), the sleeping rise-fall breath of your baby on your chest, or a row of oak trees mirrored in a rippling lake. A butterfly’s wings flap every second—flapflapflap—to keep it free-floating through the sky, dipping now and again to kiss sweet flowers. Rhythms benefit from variety too; a gentle spring rainstorm turns dramatic with an unexpected thunderclap.”
