You are so right there are many things I rather not "know" but due to my OCD tendancies I have more "issue" with some things. When I saw reports on fecal matter found on gas pumps it really started me with more OCD issues which led to shopping carts, restaurant menus, hotel remote controls and of course hotel blankets (comforters). The list can just go on and on. I try not to think about certain things and items for fear my OCD tendancies will get worse but there are some things that are rooted in my mind.
