It is true what you wrote. I have a few piercings, i used to have it in my nose, but now i only have one visible one, in my lip...but so far i must say it was never a problem...even though i work with poeple...so i have been lucky so far :) But i think, that if the piercings and tattoos are not too extreme, they are usually not a problem. And they shouldn't be a problem, cuz you are just the same person, same thinking, same knowledge...with or without body decorations :)
