WHAT POWERS THE HUMAN HEART

Perhaps a diesel engine, with an oscilloscope. I couldn’t tell you what a diesel engine was if my life depended on it. Or an oscilloscope. If they have anything to do with what you need for me to say, or do, I am sunk. But you say, they don’t. Don’t worry, you only have to be so good to be perfect, and you are, and that is good enough.
