All physical structures can sag, but only sentient beings like you and me can slouch. To slouch is to adopt a degenerate behavioral posture. One that is aware of the potential for less degeneracy, and retains within itself a seed of an ability to actualize it, but consciously takes it out of play. Slouching is a posture of self-aware incompleteness of presence; a kind of dehydrated behavioral state of lowered availability that is less than fully engaged in the here-and-now.
