You sit in your chair not moving a muscle, and simply think a thought, a thought having to do with feeling angry or sad or euphoric or lustful, and suddenly your pancreas secretes some hormone. Your pancreas? How did you manage to do that with your pancreas? You don’t even know where your pancreas is. Your liver is making an enzyme that wasn’t there before, your spleen is text-messaging something to your thymus gland, blood flow in little capillaries in your ankles has just changed. All from thinking a thought.
