Have you heard the expression -"the more you learn, the more you realize how little you know"? Socrates is credited with the sentiment, if not the exact expression.

When I read a recent article in the February 1, 2014 issue of the Journal of the American Veterinary Medical Association about neutering, cancer and behavior problems, I immediately thought of Socrates. This is the second article linking an increased risk of cancer to neutering dog. The first article was published in the open access journal PLoS One and can be found here (http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0055937).
