“How one error can have such a devastating effect on your life!” a friend said to me. She had spent summers in the same cottage for years and knew well the step from living room to kitchen. But one evening she forgot, fell, and sustained a severe fracture of the leg. I wrote at the time that she had been taken to the local hospital and incredibly, remained there for three days without treatment. Whether she will be in a wheel chair the rest of her life depends on a new way to heal broken bones.
