I work in a conservative law firm so a bear isn't really an option. Maybe once I make partner, but even then it will have to come after a long break. I cannot imagine having "stubble" here. We used to have an older gentleman who had a nicely trimmed beard, all white, but he has since retired.
Being a rugged runner at heart, I would love to grow a rough beard, just never shave, but that will either have to wait until I retire, quit or get disbarred. We'll see what happens first, LOL.
It is funny that you asked this question though, just this morning I was in the local coffee shop and noticed that I was the only male in the place without facial hair. There were other "suits" there, too.
