This headache I have right now (probably not, but it's annoying as hell), sometime about two years ago when I had a sharp pain in my side, a day when my chest hurt from bronchitis, when I thought I broke my kneecap, when I thought I broke my nose, when I flew 5 feet from a swing and hit my head against wood or cement (not sure), or still when I chipped my front tooth. Strange that I've never actually broken anything (but that tooth), but I'm glad.
