@chai2,
Tattoos and piercing are simply art, subjective to each individuals taste and perception.
On a random thought, I've always wondered that getting piercings is just asking for trouble. Cause if I was a mafia boss, or some gang lord's interrogator, all I have to do is take pliers, and slowly rip of each piercing slowly out to gain info.
The more piercings the better, for the interrogator, or even in a fight.
