I had a moustache in my teens (called "bumfluff" at first) and kept it for years.. it was the fashion. When I was in my 30's a girl who was 19 or 20 told me it made me look older, and said they were out of fashion.. Yep.. she was right.. in the whole factory only 3 or 4 ppl had them. I shaved it off and never bothered with one again.. I had sideburns for years then shaved them off, then grew them again as the fashion came back.
What she said was correct.. generally moustaches (or any facial hair) makes a person look older.. young men grow goaties because they want to look older.. and older men shave them off as they want to look younger.
When I told my menopausal ex wife to shave her moustache off as they were out of fashion.. the joke went down like a lead baloon.. I wonder why LMAO.
Oh and btw, I divorced her.. and it wasnt because of my wicked sense of humour or sarcasm LOL.
