I'm going to chime in here once on David and the
HPV issue.
My original viewpoint was the same as Brian's, but I have also come to see that for David it has made a big deal. Here he was going along doing all the right things when WHAM! that piano dropped out of the sky and ruined his life, also ruining his bragging rights in process. By finding out that
HPV is a likely source, he is reinforced by his life styles AND he can get the word out, pointing to his own case as an example. I can certainly see that it makes a difference for him for coping with OC.
