Physiological Bending
The deflection ratio of 1:1000 serves as the fundamental reference value for determining deflection. In physiology I refer to this same value, because deflection and fatigue describe the same underlying phenomenon; everything is interconnected. The 1:1000 deflection ratio is the shadow of fatigue in more than one sense. The following table presents a depiction of the journey from boy to man – of being a man – and from man to old age (though not to decrepitude) expressed as physical condition.

The example above represents living matter expressed as tabulated information. This constitutes what may be called certain knowledge. The human being — as a product, as a condition — is inseparable from this knowledge.
The next example concerns non‑living matter, such as HEB I‑sections. This too is certain knowledge. In every profile, when subjected to load, the deflection ratio is 1:1000.

Conclusion
The longer a performance continues, the greater the resulting deflection. When steel bends to a deflection ratio of 1:1000, the stress value is the same across all cross‑sections. Span length and human age express the same idea when they are related to one another. The method of examination simply needs to be adjusted so that the two can be meaningfully compared.
