As the rebar comes flying through your windshield, you flinch. You flinch as the ponded puddle at the curb is about to inundate you. An infinitesimal moment before the crash, you flinch. As would I. Similarly, we hunch our shoulders against the wind, rain, or snow. We squint at the blinding light. We brace ourselves for the verbal daggers flying toward us.
Tell me. Does the flinching, hunching, squinting, bracing, wincing, cringing, or shrugging alter the results one iota? And yet we seek these armours, these paltry shields, involuntarily. (Are they ever voluntary?)
