It's early. Is this time-stamped? I think it is. It used to be. Settings aren't important right now. Early enough that most of the world is out of my way. Drive to work in peaceful cool relative darkness. There was a time when I had no air conditioning, but I forget those days.

Concrete examples: Treadmill. Incline walking 2.3 MPH. Playing video games and walking. Doing nothing while doing something. Almost looks productive. Veil of ingenious. Momentum works two ways. I can't seem to keep moving, so I move the ground beneath me. My knee hurts. The world whirs beneath, and does not care.
There is no perfect experiment, I suppose.
