shelf life

(similar to one existing def.-but expanded!) length of time of physical and/or sexual desirability in a human. a reference to body parts 'gone/going bad' due to lack of maintenance, genetics, and/or 'human chronological erosion' -'goods' 'for sale', only at their 'prime' for a "limited" time!! a sunny, optimistic, "good personality" (other skills?) MAY sometimes offset this!
