Typically I try to stay on topic on my blog, but I couldn't help myself when I saw this talk on the TED website.  I majored in neuroscience and psychology in college, and nearly majored in anthropology as well.  One of my favorite books back then was Helen Fisher's Anatomy of Love.  Moir & Jessel's Brain Sex was a close second due to my fascination with the differences between the brains of the sexes.  Enjoy!
