Why Pee is Cool - entry #6 - "Pee, Our Connection with the Earth's Metabolic Cycle"

Here, in the final PeePeePost, is where we bring all we have learned together and find out how the act of peeing unites us with our planet.

As we learned in the last PeePost, the atoms in your body are no different from the atoms in rocks/oceans/air/etc.  Additionally, the composition of our bodies is close-ish to that of the earth's crust!!

Because of those two facts, I like to think of any kind of earth life as little tiny earth particles--walking, talking, peeing, sometimes neighborly little chunks of the earth's crust.

Humans are earth particles.

But it gets better.
