Today I brought up the internet and, par usual, I looked at the relationship articles and found one concerning the personality of a Hyperdefensive indevidual. According to the article (which you can find http://lifestyle.msn.com/relationships/friendship/articleoprah.aspx?cp-documentid=5952913>1=10822), there is a distinct reason for the defensive behavior and that is because the residual survivalist behavior left from our days of evolutionary childhood, or "lizardhood".
