This kid of discussion is bothersome because it's like a microcosm of life. We all make casual observations and comparisons and we think that is the equivalent of "research". So we end up in a situation of "what you know that ain't so". And once we "know" whatever it is, we are sure reluctant to admit that it might not be so. If I had enough hair left, I'd be pulling it out after reading this! Yeesh.
