These past few days I’ve been eating out of habit, not out of hunger. A glance at the clock. A cursory check of short term memory: how long has it been since my mouth was occupied with food and my jaws occupied with the chewing motion? This sort of thing has happened before, I am not concerned. Maybe this is a manifestation of being anxious. Maybe this is subconscious conditioning for homeless living. Maybe this is evolution at work.
