> In the US, the latter is virtually nonexistent. The state of Massachusetts has subsidized housing for the elderly. And they are closely monitored by social workers. My uncle lives in one of these apartments, and whenever he goes out of town, he has to notify the social services office. Otherwise, they will open the apartment to see if everything is okay with him. If he's gone for more than three months, he loses the right to use the apartment. Edit: minor corrections.
