The why, for tats, varies I'm sure, but it's about remembering, a need for permanence perhaps, and for neck face etc tats it's likely some sort of social statement that also likely varies.I say again, WHY?
Who knows and there are other things to wonder about. Like people who remove the mufflers from bikes or trucks or cars. WTF is that about? And I'm talking about the seriously loud variety that seems to be everywhere now.
It seems to me that it would suck being in the vehicle driving it. And don't bring up a loudish sports car or sportfish yacht, I'm talking the bike/truck/car that breaks the sound barrier without moving. What is the point of that? And they are everywhere. Thanks for your help, Blue Crab, I'm sure you'll have the answer.
