The Bible says that most of us will live for ‘three score years and ten’ – in other words, 70 years. Nowadays however, most people consider 70 the beginning of old age. This is probably why although the word sexagenarian (person from 60-69) exists, we rarely use it – being in your sixties is nothing remarkable. However, the slightly formal terms septuagenarian (70-79), octogenarian (80-89), nonagenarian (90-99) and centenarian (100 or over) are used both as adjectives and nouns: The dinner party included several octogenarian men. She was a nonagenarian when she found fame.
