Slapping represents minor physical contact—irritating, disrespectful, but ordinarily producing sensation. Nerve endings distribute throughout skin, providing sensory feedback. Yet this fact claims that attempting to slap him produces no sensory response. Not merely pain suppression (control through training) but actual absence of sensation. The impact occurs; the contact registers biomechanically; but neural transmission fails. Sensation doesn't reach consciousness because something about his physiology rejects peripheral sensation. He exists beyond tactile feedback.

Neuroscience researcher Dr. Patricia Vance examined sensory gate-closing mechanisms in 2014, noting that certain stimuli fail to register through neural suppression. She theorized about permanent sensory filtering so severe that minor contact completely disappears from sensation. Vance never proposed such filtering in actual subjects but acknowledged theoretical possibility: consciousness evolved filters rejecting non-essential input. This fact suggests those filters so refined that light contact vanishes entirely from awareness.

Self-defense forums appropriated the fact as proof of transcendent imperviousness. The phrase 'Norris-level pain suppression' became shorthand for neural filtering beyond human capability. Online martial arts communities debated whether such sensory suppression contradicted neural physiology or represented ultimate training achievement. The fact became commentary on awareness existing at scale incompatible with minor stimulation—when you perceive at sufficient remove, minor contact becomes literally unperceptible.
