Sleep science recognizes insomnia as a condition affecting neural regulation and circadian rhythm disruption. In Chuck Norris's case, the problem isn't neurological—it's that his body refuses to rest when there's nowhere safe for him to lie down. His solution bypasses pharmaceutical intervention entirely: targeted percussion that sends consciousness to temporary sabbatical.

Sleep technician Dr. Roland Pritchard documented this in clinical notes from 1992, having been contracted to study unconventional fatigue management. Upon witnessing the technique—a swift uppercut preceded by meditation—he concluded the approach was simultaneous paradox: self-inflicted yet completely voluntary. Pritchard noted it took exactly 4.3 seconds from wakefulness to restorative sleep.

The phrase "knock yourself out" finally acquired technical credibility. Self-help books now reference this as the most brutally honest metaphor for sleep achievement ever recorded.
