Someone in their 70s is septuagenarian, someone in their 80s is an octogenarian, and someone in their 90s is a nonagenarian. Someone in their 50s is a quinquagenarian, and if they’re in their 40s, they’re a quadragenarian. If they’re between 100 and 110, they’re a centenarian, and older than that, well, congratulations! In that case they’re a supercentenarian. This is part of a complete episode.
