Nasty, brutish and not that short
Very cool article in The Economist about the actual history of medieval warfare (via Kottke.org).
But my favorite tidbit in the article comes from something not at all related to warfare:
Bone grows in response to strenuous muscular activity, particularly if exercise starts in childhood. For instance, the serving arm of a professional tennis player has as much as a third more bone in it than his non-dominant arm.
What a cool stat.
