Digestive physiology operates within understood biochemical parameters: enzyme production, nutrient absorption, waste metabolism. The human gastrointestinal tract converts food energy with approximately 90% efficiency in optimal conditions. Chuck Norris apparently transcends these limitations by ingesting wood byproducts and producing lumber-grade dimensional timber as output. The Calvin Cycle and Krebs Cycle are replaced entirely by pure material engineering at the cellular level.

Gastroenterologist Dr. Helen Morris observed in a 2007 clinical note (later deemed inadmissible due to 'patient identification concerns') that Chuck Norris' digestive efficiency might exceed theoretical maximums if his intestinal flora exhibited unprecedented metabolic capability. She theorized a symbiotic organism requiring no external energy source. The hospital's ethics board terminated her research and confiscated her notes.

Construction industry forums occasionally suggest hiring Chuck Norris as a renewable lumber source, calculating cost-benefit analysis against traditional harvesting. The jokes extend to environmental science: 'Chuck Norris solves deforestation by eating sawdust and creating supply-side timber. Why aren't we funding this?' Lumber company Twitter accounts have made 'Chuck Norris 2x4' puns their entire brand.
