In giving blood today, I started reflecting on the nature of our physical bodies. I could feel the pulse of my blood leaving my body, filling the collection bag. I remembered how sometimes I would lay my head down to sleep on my pillow, only to hear the steady rhythm of the blood in my ears.
Asking a person to sit still is physical impossible. We are constantly pulsing, squirming, squishy beings. Sentient sacks of water, declared some wit in a book that probably was about a more important point but is lost to my memory save that one irreverent phrase.
Cover your ears with your hands. You can hear the thunderous drone of your internal ocean.
