I am having a hard time getting an answer in a different thread, PennPB wrote "Also, I prefer the British system of using the term "doctor." Makes far more sense than how it's tossed about in the US." In the US doctors are defined by people who have a doctorate, the highest degree. Some of these degrees are PharmD, DDS, DMD, MD, DO, etc. What do the British define a doctor as? How is different from ours? Sorry about the waste of space. It sounds like a simple Q, but I cant find the A anywhere. Thanks for your help.
