Regarding stairs…it is critical to be careful at any age. My lawyer friend recently fractured his back on his stairs….a few months ago I tripped while bounding up my stairs and bruised my shoulder. My brother broke an ankle on stairs. I’m now acutely aware of stairway risk. In all those cases it was because distractible events were occurring on stairs. But I am now hyperaware while stepping. Focus!!! Inspect and use the bannister!! It’s not just dangerous for the elderly.
