Hello once again everyone. You guys have provided me with a lot of reassurance in my hypochondriasis doldrums. I do have one last question before I part with this symposium. In my previous epistle I told of my concern with subconcussive blows. I'd like to ask what exactly constitutes one of these minor "subconcussions". This is something that has been plaguing my perturbed mind for months. I have "hit" my head several times today and would like to know if any of these can be considered one.

Thank you and adieux,

Mike
