I weighed him,took his blood pressure (血压) and invited him to take a seat in the waiting area. I saw him looking at his watch and asked George if he had another doctor’s appointment this morning, as he was in such a hurry.George told me no, but that he needed to go to St Christopher’s Nursing Home to eat breakfast with his wife. He told me that she had Alzheimer’s disease (老年痴呆症).As we talked, I asked if she would be sad if he was a little late.
