OMG that's funny!
My dad was an engineer/program manager for a defense contractor for his career - when he retired the first thing he did was grow a full beard. My mom wasn't thrilled but he kept it well groomed, although long. My stepmom (after mom passed) loved the beard.
My husband kept the same facial hair when he retired early 2014... mustache and goatee. Prior to that he had a mustache. I've actually never seen his upper lip - and it kind of bugs me.
I did not grow a beard, or even stop shaving my legs when I retired. LOL
