just a thought but I think that it just naturally evolved that way… back when we lived in the woods, when you looked around at the mountains, the trees, the horizon (or your mammuth wife ;o)), you looked up… when you hear something, it mostly comes from the sides (that’s why we don’t have ears under the chin or up on the head) and when you feel in pain, depressed and are thoughtful, it mostly comes from your lower organs… just a though of me, as I said ) |
