I have sustained a flossing injury. (Small abrasion near the inside fold of the first knuckle of the the left index finger.) The obvious culprit would be my winding technique, which appears to be slicing into my dermis like a two-bit cheese slicer. The aggressive engirdlement of floss about my index fingers also seems to cut off most of the circulation to the outer extremities of my digits and certainly a defiant stance against gingivitis is no reason to embrace gangrene. So I have decided to loosen up my grip a bit and switch over to a two-handed backhand with more of a focus on a consistent stroke rather than a baseline power game.
And despite the temptation to go on the injured reserve, I did indeed floss last night.
