Your mind has a point of reference, and that point is the side to which gravity pulls you. Same always when you look in a mirror, because you mind tells you so. Also you are symmetrical left and right, but not top and bottom. And your mind tends to compare your image with other persons; it accepts up and down, but gets confused with what is left and right when you look at yourself because it wants to compare the image with other persons. More ramblings: Something that has fascinated me for a long while when I was a child is that your eyes see all images upside down (lens affect, etc.) but your brain turns it around. So for a long time I tried to imagine seeing things as it should be, which it's not, but still is.... AAAaaargh! Either you guys down under are very bored or very busy. Bored because you got nothing to do or you are so busy with a project that you need to post something like this as a break (like I've just done, hehe).
