Have you ever been at the doctor's office and found yourself wondering why they always seem to refer to themselves as a "Medical Practice?" Well, you are probably not going to like the answer. It has to do with the fact that diagnosing ailments and providing treatment is not always done correctly. This is the reason you often hear patients asking for a second opinion. There's another word, "opinion," that leaves room for error, much like the word "practice." Therefore, professional learning in the medical world is of the most importance.
