Why does my posture collapse right after I fix it?

You sit down, you work, and within an hour you have curled around the screen like a question mark. You catch it, you straighten, and five minutes later you are folded again. This is not evidence you are failing. This is evidence you are watching for results, not for process. When I swept a floor, I did not sweep once and expect the room clean all day. Dust returns. The broom is not proof against dust — it is the practice of returning to the floor, again and again, with a light hand. Your spine is the same room. It fills with the dust of forgetting. The straightening is the sweeping. What you are not tracking is the drift itself — the slow slide before the collapse. That gap is where the practice lives, and it is easier to find with someone else's eyes on it too. Alone, you catch the end of the story. Together, you can catch it earlier and earlier.
