My wife goes to Sapporo to see her sister, who is in a care house, at least once every month.

My wife Ayako goes to see her sister in a care house in Sapporo at least once or twice every month. Today,the weatherforecast said it would be a fine day all day,so she decided to go by her car. Her big sister Emiko had been in a care house in the suburbs of Sapporo city for several years. She had lived with her husband in a condominium in the center of Sapporo city before, but she came down with a disease of her brain. Her disease was something like Alzheimer's, but the doctor said it was not. What was worse,her husband,who used to be a principal of senior high school,suffered cerebral infarction,and became unable to live without a wheel chair. That is why Emiko entered the care house. She had been a very bright woman and been able to do anything very well. But she became unable to do what she could have done easily before. Now she cannot speak, walk by herself, and cannot even recognize who are around her. Emiko is now over eighty years old,and her husband is eighty-four, I heard from him last month. When we have grown old, can't we avoid facing such difficulties? I am afraid my wife and I may fall into such difficulties ourselves in the future.
I stayed at home and worked on our garden doing what I had left half done yesterday.
