Question: why the beard?

Why not? I guess I
could say it's because I'm not a low-T, beta soy-boy. On the contrary, I'm more of a high-T, alpha, meat-eating conservative. hahaha
But a more serious answer -- St. Matthew had a beard. I'm not a Baby Boomer, so I never understood the whole "clean cut/clean shaven/look like a 12 year old boy" thing. Let's just say that "clean-shaven as a virtue" is not part of my values or culture at all. I have more in common with Millennials in this regard. For me, a beard (or the ability to grow one) is a sign of testosterone and general manliness.
As my hair started thinning on top, I chose to grow a beard instead. I've had a beard about like this since 2012 or so. The beard, together with my general muscular build (I have forearms like Popeye), makes me seem scarier than I actually am. At least when I'm not smiling. I've actually never been in a fight.
