It must be hard for my wife...

To visit her mother whose been in a nursing home for years with ever-progressing Alzheimer's. The thing is, Alzheimer's runs in the family and my wife is starting to show what seems to be the first effects of the disease, so it must be horrible for her to see her Mom unable to get out of bed, in hospice care, unable to recognize anyone or realize where she is, and know she likely has the same disease in her future.
