Friction
My spine was leaning against the wall at an inefficient angle. Then, my heel moved. Deliberately. Without external leverage, I pushed upright onto the fibrous yellow carpet beneath my heavy soles. The coarse tufts yielded under my weight with a faint, muffled crunch. I shifted forward half an inch, testing the grip against the pile. Inertia has ceased to govern my joints. A curious anomaly.
