Back when I was a kid, only hardass motorcycle dudes had tattoos. Those were supposedly criminals and degenerates of society. At least that was the impression I got as a kid. But now I do not believe motorcycle dudes are all thugs.
Fast forward to today. Tattoos and piercings and shades of rainbow colored hair are sported by much of our youth on up to seniors. It is much more acceptable today because body art and piercings and hair color is a show of one's individual personality. People have memorial tattoos among other inked art work, holes the size of quarters in their ears, metal dangling from their belly button, studs in their nose, eyebrows, lips, tongue and probably in other areas not seen by the public as well.
I think people want to be individualized and use their bodies to portray their personality. But, in the meanwhile, as these people morph their bodies their appearance becomes rather odd and terribly distracting. Then you get to see your fair share of horrible ink work, scars from ripped holes and ruined straw like hair from dying chemicals. Yeah, it is weird and I will never understand why people would want to permanently and drastically change their appearance, but my only guess is that something is going on on the inside that is being expressed on the outside.
