I've been finding myself tripping on things a bit lately. Mostly it's more like scuffing the ground with my shoes. Only once did I come crashing down to the sidewalk. I was running at the time so momentum was harder to halt. Trying to avoid head butting a palm tree I shimmied left and landed heavily on my elbow and grazed my knee. Concrete is not forgiving!
But it finally dawned on me as I was walking to the store a few days ago and I again scuffed my shoe on a slight rise in the pavement while crossing the street. My downward peripheral vision has been blocked.
As annoying as it is to wear a mask (and believe me, it's really annoying to run in one) I didn't realize it was affecting my vision. We tend to look far ahead and as we walk and run. Things underfoot tend to pass magically under us. But it's not magic is it? Some part of our brain is still paying attention to that lower field of view.
Interestingly, I don't trip when I'm walking home from the library and start reading a new book on the way. Maybe that creates such an obvious distraction to my vision that I'm paying closer attention, consciously and subconsciously, both.
So I've been trying to focus on keeping my toes up so as not to trip so much. And my knees up. And my eyes up... And my spirits up!
