What Genghis Khan, but Elizabeth Can't

One of my ongoing research projects is on the Mongol invasions. Doing some background research, I realized there's an interesting asymmetry between male and female rulers, in terms of available imperial sexual strategies. Say that the Mongol hordes have just finished annexing another city along their ever expanding frontier. Let's call it Elbonia . In this case the local elite had the good sense to surrender peacefully, and accept the Mongols as their rightful overlords.

Or you can sell all of them for $400, and they will all go to wall street types. It seems a no brainer, but what happens if the next album flops? In the first case, the guys that followed the band from the garage days will still go to the concerts to hear the old songs, and maybe your next effort has a better reception. Even if you never have another hit,...
