I have one.
Why do Mexican gangsters cover their faces in tattoos?
If I was a gangster, I wouldn't want to be easily identified by la policía. If the idea is to look menacing, why not apply henna tattoos? In The Dark Knight, The Joker could not have passed for a cop and shot Gordon with his make-up on.
Face tats also, of course, drastically reduce job opportunities, because it's difficult to take people with facial tattoos seriously.1
an unwise investment
While I don't expect gangsters to ever pursue lawful employment, what if you want out someday?
I've been suffering from gushing nosebleeds in my left nostril. The Internet recommends not blowing my nose, as doing so may rupture the alleged clot.
I'm also sick, and my cold has entered the runny nose stage.
So far, so good.
