This amazes me too, Doc. It's a little scary, isn't it? I've used the word scary in a few of my answers.. . I liked your answer to TATON the other day. The thirty year old with chest pain. You recall.I'll look for more answers from you. The medical catagory is about all I can stomach at this point. It's amazing, as well, the questions some ask. . . Take care.. . K.
