Retarded aging

Retarded aging, despite its politically incorrect nomenclature, is a super-power that represents individuals who age at a much slower rate than a normal human being. This power may also be common amongst some terrestrial and alien species, as well as supernatural creatures. The DC Comics superhero, Alan Scott - the original, Golden Age Green Lantern, was infused with the mystic power of the Starheart, which completely altered his physiology. A side-effect of this is that he ages much more slowly than a normal man. In the modern era (barring any extraneous effects), Alan Scott appears to be a man in his late forties or every fifties, even though he is well into his eighties.
