I'm a regular old guy from Ohio. I'm in college (still) and I've learned a couple of things.
1. Bookstore math: A book that costs $120 at the beginning of the quarter depreciates to $.12 and half a slim jim at the end of it.
2. NO ONE is completely sure about ANYTHING. For every crazy theory, there is someone in academia who believes it and has written a book about it.
3. Looking at campus "police", I found out where they train Mall Security.
