If lightsabers ever become real, and let's be honest some genius will dedicate his entire life into making that happen, I hope the entire world will be well practiced in how to handle them. Sure the ballet of Star Wars characters fighting in light sabers looks great (or ridiculous), but when you get an up close view on the sword fight? The whole world will be missing at least one of their hands.
