We're not sure why, but Christine has to stay longer. The heart diagnosis is good, and almost old news by now. So far as they can tell, her heart is fine, but now apparently they have found some lung problems. Christine has always had a chronic sinus infection since we have been married. It comes and goes, and we have seen several doctors about it, and nothing seems to work for very long. Not that the doctors have said anything about it today, but I have always worried about her respiratory system since 1989. They have now ordered a PET scan and other tests.
