I got to about the 27th century BC and decided that I wanted to backtrack to go through periods of prehistory: Trying to do all the possible connections was just too tedious. But I have made some progress in other areas.

For one, I have finished a review of how other sociology applies to Asiatic peoples, and have begin reviewing religion. For another, I have finally finished connecting biographies to social mechanics, and I am now in a position to consider why the people selected for the biographies were important. For a third, I have finished reviewing connecting nations and cities to culture, and done a review of how peoples are applied. I am now in the process of reviewing how institutions are applied to culture.
