Added to this, my recent propensity for falling, in various categories: big, looping, hyperextended, “Ministry-of-Silly-Walks” falls; face-planting due to festination (where I’m tiptoeing and leaning “over my skis”); and plain old tripping due to foot-dragging and irregular gait. The latter two are Parkinson’s disease, but the first, the big dramatic tumbles, are linked to something else.
