When I realized I needed an image of a completely hairless head for my page, I immediately though of phrenology. You know, the "science" of determining one's personality from the bumps on one's head. I found a phrenology "map" which made an excellent navigator.

If you're a true believer, don't fret. There are plenty of serious sites on the web about phrenology. None that understand the scientific method, but you just can't argue with faith.

I prefer the rationale of the page I swiped my beginning graphic from.
