What is Treadmill-running?
1.
1. To run upon a treadmill, (a gym machine for working-out).
Benefits to treadmill-running as opposed to taking a sidewalk: no traffic, no sidewalk problems, no beggars (or thieves, or gangs), easily-accessible pre-paid water, can listen to music loudly and not compromise personal safety, no jerks staring/commenting, don't have to wear any travel items, and best of all: NO WEATHER ISSUES!
Treadmills are especially beneficial to anybody "laying low".
2. The daily grind for a dress-suit corporate slave.
ie. My life... is treadmill-running... at the office... at my gym... in my personal life... and in my mind... This is the point where the movie begins.
