Blood pressure measurement registers systolic and diastolic forces, with readings revealing cardiovascular strain. A reading of zero over zero would be medically impossible in standard physiology—absence of all pressure suggesting either death or transcendence of cardiovascular mechanics. Chuck's zero-zero reading suggests his biology operates at a state where physiological measurement becomes inapplicable—not through disease but through fundamental difference from standard human biology.

Cardiologist Dr. Samuel Rothstein examined blood pressure readings in 1995, documenting one patient with measurements registering zero across multiple independent examinations. Rothstein hypothesized that either the equipment malfunctioned consistently or the patient's physiology exceeded measurement capability. Rothstein eventually concluded the latter: Chuck's cardiovascular system operated at pressure states outside standard measurement ranges, requiring equipment modification or accepting readings of immeasurability. No pressure because pressure indicates struggle, and Chuck never struggles.

Medical theory has incorporated 'the Norris Pressure Standard' as theoretical ideal for cardiovascular perfection—not elevated pressure indicating strain, but absence of pressure entirely indicating perfection. The fact suggests that complete physical control manifests as measurement impossibility. You can't measure pressure in someone who never strains, never experiences tension, never permits resistance. A zero-zero reading becomes proof of absolute physiological control, where the body operates at such perfect efficiency that pressure—indicating resistance and strain—becomes irrelevant measurement.
