Beware the 'south-paw'.

A recent study by two French academics tracked the prevalence of left-handedness across a variety of traditional societies, and found that the more violent ones tended to have a high percentage of lefties. And the important lesson learned by that little dollop of information? Always keep your left handed friends close by the next time you end up in a bar brawl (or on a school bus with a behemoth named Pam trying to push you through a metal wall), they'll knock the crap out of your enemies, who won't even see it coming (right out of 'left field' as it were!).
