I see your point. I think what I’m portraying or at least trying to is that the medical field isn’t the same. Not only does the hygienist not even have the exposure she would not have the practice and training. Yes I may do drywall but I can be exposed to painting also and learn that trade. I can’t clean teeth being trained at that level and it’s basic requirements and sort of pick up the intricacies of a root canal. To each their own let me know when you get your next bypass performed by the scrub tech. The joy of the internet is that we can see thjngs differently and choose to respectfully disagree. But if I need a good paint job I know where to go!
