That sounds very interesting. Weird fact about me, I have always been interested in languages my whole life, but as a child had a hard time getting interested in history. It's only as an adult when I realized how much of understanding relationships among languages IS understanding the movement of people and cultures that I was able to find a way to sink my teeth into history and really start learning and retaining some. Linguistics saved my intellectual curiosity!
I can relate! I love the persistent mysteries that linger throughout history by means of language. It seems to me that Ostler, Deutscher and David Crystal have pretty much got the "mass-market" linguistics field sewn up, although Crystal's focus is on English.
