Cal, I am not sure what I mean either. Perhaps this due is my problem with the word know. For example, in German there are two words for the verb to know, wissen, to know for a fact, a scientific sense, and kennen to be acquainted with. English to know is vague. I guess we simply go by context. This the sense of ordinary language. I suspect one would have to expand the word know to be more precise. But that probably will not happen. All I know is that I have never had a sense of knowing my face, or body for that matter. I know people who always look different to me - sometimes I do not recognize people I know. Other people look pretty much the same to me. Sub normal people always look the same as they have no nuanced looks. For example a catatonic, particularly the full blown one's with waxy flexability and pale white skin, look the same all the time. I once had the experience of viewing someone I really knew slip into a catatonic state. To make things more interesting, I have people who claim they saw me somewhere and they do not like it when I tell them I was not wherever they thought I was - I handle this with a smile now. At my age I seem to look more and more like others of my age group. I played tennis on a regular basis with some friends who allegedly looked like me. People did not confuse us when we were together. Perhaps it is easiest to say I do not recognize my face or body - after all they are borrowed. I will have to think more about your main question. Your " different several ways" might help - if you would... Stu
