Oh, do be careful on steps in the winter! A few years ago I stepped back outside to unload the car and slipped on ice on the top step. To prevent what happened to Robert, especially fearing neck or spinal injury, I tried to catch myself with a hand. That splayed my fingers apart, resulting in tendon damage that left two fingers free to sway back and forth, initially preventing me from grasping anything. The damage mended some, and I did exercises to build the adjoining muscles, but there are still some slight affects after a decade. As kids, I'm sure we wondered how people got hurt falling down stairs, but now we know! Good reminder.
