I never thought the human heart was a beautiful thing until my youngest son did. It has always seemed clumsy, relatively simple,and a somewhat gross *****. Muscle-ligament-electricity I have always been bewitched by the brain and its nerves. it's mystery, complexity and resilience. He loves blood the way I love nerves, he begs me to re read the heart and blood pages in his children anatomy books. He knew all kinds of facts about blood and the heart at 2. He never drew the traditional valentine days hearts he draws, to the best of his ability, anatomically correct hearts. He loves it's rhythm , he loves it's simplicity, and he finds it above all else, beautiful. he loves it for its tangible nature, the way it is reliably one way and one way only.
