Hello PanPiper: Well... I'll defer on suggesting possible explanations regarding your questions. Perhaps other members will want to weigh in. Our purpose here on PC is primarily to support one another (as individuals who have mental health concerns) as well as to share information & experiences. So I guess one question "back at you", so to speak, is if there is some personal concern with regard to this or if it's just curiosity. You don't say in your post. Anyway... I see this is your first post here on PC. So... to PsychCentral… from the Skeezyks! May the time you spend here be of benefit.
