One thing I don't think I've ever understood among people, my peers especially, is the general disinterest of history.
It's hard to say exactly when I became especially intrigued by studying history, aside from all the hours I would spend watching various and random specials on The History Channel as a kid. It was never a stand-out subject in school for me, not like how I enjoyed writing and sometimes English, and always hated Math, but I remember never minding History all too much. Aspects of it, such as studying the Greek gods, or the Egyptians, were things I remember enjoying without really realizing it. And now, with more knowledge and more capability of knowledge, history is even better and easier to appreciate than it was before.
For anyone interested in real, raw, deep history, I would highly suggest the book "A People's History of the United States," by Howard Zinn. It isn't for the faint of heart, so to speak, being that it speaks such harsh truths about our history, but it's a highly educational book, the kind that doesn't seem to make it into school textbooks for the same reasons that it's such a great account of history, a large part of that being controversy (another part of history that I love: the debate, and the controversy.)
It's still funny knowing that Christopher Colombus didn't cross the ocean because he wanted to prove the world was round (something we are taught so that it makes sense at a young age), but for a very different and indeed possibly controversial reason. Or knowing that Ponce De Leon was not, in fact, looking for the fountain of youth, for example. Or that America wasn't always the good guy as we are often taught, at young ages, to believe.
I'll never forget discovering in a U.S. History textbook one year, that the entire issue of President John F. Kennedy's assassination was covered in a single, plain sentence. For me, this in particular was especially frustrating, being that I had just finished reading "11/22/63," by Stephen King, which--although fictional in story--contains a great amount of actual history involving the case of JFK's assassination, and even addresses the still uncertain possibility that Lee Harvey Oswald wasn't the actual assassin. Of course, controversy isn't always the best teaching method and I understand many of the reasons why history is taught the way it is, I still think there should be more truth taught in schools regarding history at all, and sometimes that is thankfully the case.
But being a sort of nerd for history is always, in some ways, fun: being one of a select few of my friends excited for the movie "Lincoln," directed by Steven Spielberg and starring Daniel Day-Lewis, for example, was a neat feeling. There's always more to learn, more to debate on, more to wonder about history, and of course a lot to learn from it, too.
