atmospheric pressure, my lungs, and daft beings

Source

The scarcity of public transportation on this appropriately rainy morning was the impetus for hind leg activity from point A to point B. And since our lower extremities are voracious oxygen consumers--as a result of mitochondria-filled skeletal muscles--I found myself relying on my thoracic (intercostal) muscles to systematically expand my torso (to decrease pressure) and allow air to ventilate my lungs.  This sequence of realizations has led me to think about density. Density has various subject matter-specific definitions. I would sometimes just think of it as level of crowding. Too much stuff. Too many people. Too much particles.

People are occasionally described as dense. I think I can be dense. Filled with thoughts. Thoughts about how the strings of the universe are conspiring against me. The usual. And then there are other dense people who are so impenetrable--who just don't get it. Even Thor's Mjolnir wouldn't be able to crack their myopic and deafened state so as to turn on the light bulb of "there's something that needs to be done."
