Take the subject of history.  According to Wikipedia, “History is the past as it is described in written documents and the study thereof.  In Middle English, the meaning of history was “story” in general”.  Stories from the past inform our present and our future; our influence and learning tool left to us as a legacy from past generations.  And we pride ourselves on handing on a legacy of knowledge through our bodies of work and stories we hand down to our interns and trainees, our children and our friends.
