Thankfully, there were only 3 stairs to the landing and I caught myself a bit by smashing my elbow into the railing and flailing about. Somehow, I managed to avoid whacking my head on anything, which is pretty much a miracle for me. When I fall I always whack my head, it's like some sort of law of nature. But this time I was lucky and just strained my ankle and skinned my elbow.
This still pisses me off mightily. I'm gimping around today on a sore ankle and I spent all yesterday elevating it so that I could walk today. Stupid brain/body disconnect. You'd think I'd be done tripping over nothing at my age.
