Doctor?

One of my junior tell about a lecturer asked them, "What it meant to be doctor?"

Hmm interesting enough that doctor means:

From Middle English doctor, doctour "an expert, authority on a subject" from Anglo-Norman doctour from Latin doctor (“teacher”) from doceō (“I teach”). Displaced native Middle English lerare "doctor, teacher" (from Middle English leren "to teach, instruct" from Old English lǣran, lēran "to teach, instruct, guide", compare Old English lārēow "teacher, master").

So to be a doctor is meant to be a master of your field. And to be a doctor is to teach & educate others...So have we fit our role as a doctor-to-be?
