I know it is common, but it really burns me that people in the medical profession -- 'experts' in their field do not even do the slightest thing to educate themselves in advancements in their own line of work that might benefit the patient without padding their own stinking pockets. I guess you can equate it with people in other lines of work who plod along in their jobs doing the bare minimum, but I have never understood it when it comes to monkeying with people's LIVES how anyone could be so callous and LAZY about it. Gosh, why not spend a LITTLE time reading up on things, or at least investigating it a bit when it is something as simple as swishing to see if there is any noticeable improvement while doing it a day or two themself.
