There is an interesting biased article from "Ladies' Home Journal" (LHJ.com) called "What He's Really Thinking When You Fight". by Marianne L. Legato, MD (actually her name is Marianne J. Legato, MD, but the article displays the wrong middle initial).
The article is broken down into 4 sections. 1) Where the Problem Starts. 2) Anatomy of an Argument 3) Where Chemicals Come In 4) How to Fix It
