Ditto what Kim and Macloudt said.
Also, sometimes assisted living or a nursing home is a necessity. And sometimes it has advantages beyond the basic caregiving/safety issues. My father was in assisted living for three years, and he enjoyed the activities and the people. He was a handsome and funny widower, and the little old ladies fought over him. The one who won was very sweet and had about the same degree of dementia as he did. I can't tell you how cute they were together!
