How cocky was your great^10 grandfather? Up to 3 million men may be descended from an Irish King. Impressive but still well short of the estimated 16 million ancestors of Genghis Khan. Does the alpha male mojo that drives leadership also make a man a horndog or does being a high status male simply give one the opportunity that all men would gladly have? If you aren't constantly on the lookout for a new hen, perhaps you're not presidential material.
