David has always been curious. "What if...?" was his favorite question as a child. In high school that curiosity got him into trouble, in college it ... well it got him into college! But all of the classes in history, philosophy, literature, theater, language, economics, anthropology, and political science didn't assuage that curiosity, they honed it.
He also discovered early on that writing novels and lyrics and short stories and articles gives him the excuse to pursue any and all questions he might have into all sorts of curious places. And the answers he has found would fill a book! More than one, actually.
