I've heard this theory a couple times, and I have to say it's kind of unsettling to think that my personality and termperment may be just as much a product of which infectious organisms my body contains as the behaviors I have picked up from the people around me.

I've had cats all my life (outdoor cats), and I match the description of most of the personality effects described. That said, the author also felt she matched alot of the symptoms of the infection, but ended up being clear. I guess in the end it's just one of those things where you have to push it out of your mind and just get on with living life.
