We inhabit a planet that is hurtling through space in orbit around the sun. Gravity exerts its force on our bodies within a curved space-time. Our bodies reflect this. There is nothing linear about them. Our spine is often thought of as the straightest thing in our bodies. And yet our spine is curved. Our ribs are curved. We are filled with undulations. Our bodies are not meant to be static. --- **Related** [[The body as a mental process]]
