On Belly Buttons, Umbilical Cords, and Severing That Tether

Belly buttons in particular are so interesting to me because of their connection in the womb.  The funiculus umbilicalis was our original cord that tethered us to our own mother Earth.

You are literally the entire planet to your baby in there. Babies in the womb are like astronauts- both are in a protective, isolated environment, floating in a world of their own. Just as an astronaut relies on life support systems, the baby relies on their mother for those same systems.
