[Phantasm]

Hebe-2 - On this world, supers (and only supers) either don't age or enjoy highly reduced rates of aging - so long as they remain active. This includes super-normals and tech-users who don't otherwise have powers but still engage in activities that can be considered "superheroic" or "supervillainous". Some folks will age at a greatly reduced rate, having been active in WWII and still active today while looking only 20-30 years older (these will always have gray/silver hair, either fully gray/silver or just at the temples). Others seemingly have stopped aging altogether. Once they retire, however, they resume aging at a normal rate. Coming out of retirement - or even just entering semi-retirement by acting in a supporting role to another super - restores the reduced aging factor.
