A wise man once said, "When I have a little money, I buy books.  If anything is left over, I buy food."  Well, considering most of the hombres hitting this website have probably been banned from as many buffets as I have, I'm not suggesting that extreme a devotion to the development of the intellect.  I am suggesting, however, that if the number of barbell plates you have in the basement exceeds the number of books you own, then perhaps you should heed the words of Ben Franklin: "If a man empties his purse into his head, no one can take it away from him.  An investment in knowledge always pays the best dividend."
