HN Age

"HN (Human Normalized) Age is the method of comparing ages of races with varying lifespans to one another. It is implemented with a simple comparison to a human's lifespan, about 100 years, to determine the relative age of the person presented. For example, a Shra can live for up to 500 years, so if one claims to be 200 years old, its HN Age is 40 years old, well into maturity. The use of the HN Age system came about from the Human domination of trade and agricultural industries, and the need to determine when a worker from a non-Human race had become too old to be put to manual labor. Some non-Human people hold the age system with disdain, but most learn to accept it, lest they forfeit their human-funded retirement programs."
