I walked down to work, walked up the four flights of stairs to my classroom, walked back down, then immediately walked back home every day for a summer (when he was otherwise off from work due to summer break).
This performance was basically a structured way to get some exercise. Somehow, however, breaking all the laws of physics in so far as the conservation of matter and energy go, I did not lose any weight.
This performance, which lasted about 60 minutes per day, is undocumented. It builds on Back, 21, Walking a Fine Line Between Here and There, and other walking performances.
