This has been dawning on me in every single dance class for the past two weeks, so let me inflict it upon you. The steps might seem a tad counterintuitive, but trust me, they work wonders.
Acquire a deep dental filling in one of your upper (maxillary) molars. It is imperative that the filling be in an upper molar and so deep that your dentist invokes the name of root canal. As in «If this doesn’t work, you’re going to need a root canal.» Step one is difficult and, depending on where you are in the world, rather expensive. It is slightly easier if, like me, you’re predisposed to bad teeth.
Acquire a common cold. Any upper respiratory infection will do, but a minor cold is easiest to come by and comes with the least side effects. This step is neither difficult nor expensive. Nor, in most cases, possible to avoid.
Having acquired the two prerequisite… items, proceed to modern class. Notice immediately that the sinus irritation from the cold causes the nerve next to the filling to twang every time you land too hard from a jump or bump your head. Rapidly learn to land like a feather and to keep your head on the floor whenever possible during floorwork. Remember to take some ibuprofen before next class.
Disclaimer: just for the record, I don’t actually recommend any of this. Duh.
