changes associated with normal aging that are inevitable and caused by intrinsic biological or genetic factors. Examples include the loss of melanin, which causes gray hair, and decreased skin elasticity.

the fact that a single prominent characteristic of a stimulus accounts almost entirely for preference for the stimulus generally, with other characteristics being largely ignored.
