Good point. You gotta do something to keep them busy,and sending the kids off to be used as cannon fodder is a tried and true tactic. As a sidebar of sorts,I remember reading somewhere that one of the reasons for the Norman Conquest was that William the Conqueror(a few years before he had "Conqueror" added to his name)had a surplus of knights and a shortage of manors. The shortage probably wasn't the only reason for the conquest,but having a war handy sure gave him something to do with the excess menfolk,and after the war was over,it kept them busy trying to pacify their new subjects,instead of troubling William.
