Why do people get tattoo's? Is it because it's the norm now, you're friend has one, you think it looks nice, so you get one? Even if it is, how did it ever become the norm? I'm sure tattoos used to be a thing for people who belonged to an uneducated class and had often served time in prison. Maybe other people started getting them to express some kind of solidarity with such people? Or maybe it's a form of protest? You knew it would piss off your parents and what better way to demonstrate your indepedence and contempt for authority (the key to a healthy young mind in a modern society) than doing that?
I've never seen one that enhanced a persons looks, or made me think that person was someone of any depth... The "live for the moment" personality is usually one of great shallowness.
