Surprised at the automatic slackening of my pace as I start my ascent of the hill…. Perhaps the hill automatically shortens one’s gait so that, to continue at the same speed, one needs actually to move quicker or lengthen one’s stride as you start up. Still, I’m surprised to find my pace has slowed as I begin to climb without me having intended to go any slower, just as if I were an object that had been rolled up the hill rather than a lifeform that would be naturally inclined to retain its rate of speed in the face of an obstruent. A natural inclination to maintain the same number of steps per minute, not meters per minute, perhaps.
