zigbot, what I neglected to factor in is skin color. The theory on hair density I just read factors in the need for UV protection. Africa, dark-skinned thus ideal UV protection and little visible body hair. Greece, light-skinned not so good for UV protection so thicker body hair is required for that protection. Norway, little UV protection needed, so light-skinned, but additional body hair for insulation.

It is my opinion and I am unanimous in this, because it is my opinion, which is, in fact, mine.
