Apparently, our following of politics affects us in ways I was not previously aware of.
In an October 21 article on Wired, the author examined the results of a study that measured the testosterone levels of men using their saliva. The result was that "liberal testosterone levels stayed stable, while those of male Republican voters plummeted. The latter also reported feeling submissive and unhappy."
I will leave it to the reader to examine the research and whether or not to use it in class.
