LOL, Genghis Khan has way more up his sleeve than you give him credit for. Show me a U.S. president that had about a thousand 1st-generation descendants. 800 years later - today - Genghis has about 15 million descendants. This is based on hard science genetic testing, not historic record, by the way. An average male person living 800 years ago has a bit above 500 descendants living today.
