I wanted to for years before I was “allowed” to 😀
But when I hit 40 the Mrs was like “OK, it’s time now”. I think I got out before achieving the full-on “egg in the nest” look, which is pretty much what I wanted.
I would echo what others have said about maintenance. When I had #3 back/sides and scissor cut on the top I could go five weeks between haircuts and it’d mostly look OK. Now it’s #1 all over if I don’t trim weekly it starts to look bad (or possibly worse).
Interestingly, the barber’s is now more expensive. I feel it’s an insult to their art to go in and just ask for #1 all over so I get my beard done too…
