Newton’s first law famously describes inertia: a body at rest tends to stay at rest, and a body in motion tends to stay in motion. This is not only a law of physics, but also one I have, after much research and investigation, conclusively proven applies equally to humans.

For example, when it’s time to lay down and go to sleep, I find the comfort level of my bed is somewhere between a sack of bolts and a bed of nails. No position is comfortable. My feet are too hot and my face is too cold. I resist lying there and resist falling asleep. But when it’s time to get up in the morning, my bed is heaven on earth. Perfection personified, and it practically takes an act of Congress to get me to leave it.

Same for the shower. I dread that routine. But once I’m in, luxuriating in the cascading warm water and sudsy shampoo, I want to never set foot on dry land again.

Curse you Newton and your inertia.
