And along that same train of thought (I was an undergraduate history major), I always thought it would have been smart to incorporate left handedness into infantry formations in the ancient world. The Greek phalanx was famous for drifting right (...right?), as each man would seek the protection of the shield of the man next to him in battle, and it often influenced the course of battle—not to mention that battle lines were often drawn along natural boundaries (rivers, mountains, woods, etc.) to prevent an entire flank from being exposed to the enemy. Now, wouldn't an obvious solution to that problem have not been putting a couple columns of left-handed infantry soldiers on the right flank of the formation? Voilà! No exposed flanks, and less drifting.
So, instead of like this: Like this:

This is probably why I don't have a girlfriend.
