Body Adornments and a Career?

termilitor asks: "I was thinking about decorating myself with a tatoo. The only argument that holds me back is whether this will affect my career of a mathematician / computer programmer negatively. I would like to ask readers of the Slashdot if they have such experiences, including other types of self decoration, like body piercings and dyeing hair." It's always important to look professional when in the work-environment. The big question, of course, is how many of you believe such things are mutually-exclusive. Wearing a tattoo is a non-issue with the right clothes, but what about piercings and hair coloring? Can a happy medium exist between self-expression and the professional environment?
