<i>Places where there are others just like them.</i><p>Gross.  I get that some people get to places in their lives where they don&#x27;t want to deal with diversity, but I don&#x27;t want cities to turn into places like that.  Retirees (those who do want to stay, and don&#x27;t want to live in a retirement community) are a part of that diversity.  Shipping <i>anyone</i> off involuntarily (or even semi-involuntarily, in the case of ridiculous housing cost swings) is completely unacceptable to me.
