when i walk around the ward pushing my little IV-stand, i refer to it as orbiting. its part boredom relief, part exercise, but in itself its pretty monotonous, too.
ive realized the hospital has posted little signs that calibrate on the elevator lobby, showing distances. a single triangle-shaped "orbit" of the tenth floor is 155 meters. but before noticing this id already worked out my own calibration. i prefer to do a "half-orbit" which cuts off most of the west ward where all the most depressing chemo patients seem to be, and by counting paces id concluded that a half-orbit was almost exactly 100 meters (so on the floor plan its more like a two-thirds-orbit).
thats a very convenient number, because i can know that ten half-orbits make a kilometer, etc. so i just walked a kilometer. im going to shoot for two or three each day (20~30 half-orbits), thus equaling my daily walking commute to work.
