Beards are made 4 horrific facial scars
Scars are not self inflicted usually so it's apples and oranges. Just like an old dog they built up.160 stiches in my face 138 just under my eye. 233 on my wrist hand fingers left. They did extensive reconstructing my orbital socket in 88.
Tats are chosen life stories you want to remember. Scars are to remind you of experience. Don't do it again a reminder of stupidity or reminder of negligence of someone else.
Branding is a tat thing so are mods and piercings.
