Question

Why don't we feel the pressure of air columns above our head?

Answer 1

Air does not crush you down. As a fluid, air flows around you and tries to crush you in. Fortunately, there is typically just as much pressure inside your body pressing outward as there is air pressure outside your body pushing inward. They typically cancel out, meaning that there is no overall force on you and you don't get crushed. Even when the internal and external pressure don't exactly cancel each other out, your skin, muscles, and other tissues are usually strong enough and flexible enough to not be damaged by the force.
