I think many people are stuck on the fact that people of certain professions need to look a certain way, according to them, of course.
I wouldn't bat an eye at a doctor or lawyer or teacher or... anything, really with tattoos or facial piercings, mostly because I'm in California and I don't know many people who do not have said piercings and tattoos.
A friend brought up a good point- she has numerous tattoos on her arms, back, etc... and she's an infant health mentalist. It doesn't change the fact that she is wicked smart and has her own business. She is what she is.
I tell people I have tattoos and they get this shocked expression and it is usually followed by "no way" or " I don't believe it!" lol Uhm, yes, yes, I do. I think people need to get the stereotypes out of their heads, times are changing!
