@matigo That looks a lot like what I trim my beard back to. I use an 1/8-inch guard on a buzzer whenever I decide it’s gotten annoyingly long and shaggy again. The hair density is pretty low.
I probably could have grown a full beard in 8th grade - I sported mutton chops throughout high school (facial hair must be above the bottom of the ears? let’s go right to the limit!) - but I always had a wimpy mustache until my mid- to late-20s.
