the obvious reason patients don't want their nurses and other medical specialists to have body mods is because they have certain iamges of the archetypical nurse/doctor in their head, and if they don't conform to that archetype, then they might think that they're a bad doctor/nurse, because they aren't *appearing* to be *like* a doctor/nurse. so I can understand why people might be disappointed by a nurse or doctor with body mods, but that's not to say that I think that this should be the case - tattoos and piercings also, however, happen to suggest youthfulness, as you tend to only see younger people with tattoos/piercings. therefore, that youthfulness might appear in their minds as a lack of knowledge and expertise. but, again, I don't think people should be so quick to judge like that.
