You sound like an idiot.

History has nothing to do with emergency medicine, nor does tattoos.

I took AP history in high school and that's not helping me one bit in nursing school currently. I also have a tattoo on my wrist and none of the patients I help care for during clinical seem to care about that as I help them to do things they can't do for themselves.

You may find yourself in an awful situation one day rethinking this opinion of yours.
