“You are comprised of 84 minerals, 23 Elements, and 8 gallons of water spread across 38 trillion cells. You have been built up from nothing by the spare parts of the Earth you have consumed, according to a set of instructions hidden in a double helix and small enough to be carried by a sperm. You are recycled butterflies, plants, rocks, streams, firewood, wolf fur, and shark teeth, broken down to their smallest parts and rebuilt into our planet’s most complex living thing.
