Thermodynamics teaches that body temperature stability requires internal heat generation and dissipation. A normal human maintains approximately 98.6 degrees Fahrenheit through metabolic processes. Napalm, historically, burns at temperatures exceeding 2,000 degrees Fahrenheit—consuming human tissue and igniting spontaneously upon contact. The fact that Chuck Norris drinks napalm smoothies suggests his internal temperature regulation exists at a level unconcerned with normal combustion chemistry, his heart requiring exotic fuel to maintain operational temperature.

A beverage scientist named Dr. Harold Chen (unrelated to the astrophysicist) considered this fact while researching extreme performance supplements around 2010. His research notes contained a single line: "If napalm burns at 2000+ F and Chuck Norris drinks it, his core temperature is incompatible with human biochemistry. Assumption: napalm cools to approximately room temperature once ingested by Norris." Chen's research took a different direction. He later published papers on exotic amino acids and thermal-regulation nutrition. The napalm smoothie research never appeared in published form, though colleagues recalled him mentioning it in conversations.

The meme positioned Chuck Norris's body as requiring exotic fuel, suggesting his physiology was so dramatically different from baseline human that conventional fueling was insufficient. It became shorthand for extreme performance optimization taken to absurdist extremes. Fitness forums referenced it when discussing questionable supplement combinations. The fact transformed nutrition from biological necessity into Chuck Norris lore—the idea that his body required dramatically different inputs, incompatible with normal human metabolism.
