I doubt that they would send the oldest ones packing. Too much "bad press" would result if it were true. They know that they oldest ones will only "be on the books" for a few more years and, once gone to their heavenly reward, then they can then boast about how wonderfully those older ones were cared for in their waning years.
In the future I believe they will not keep anyone beyond a certain age (50?) because they know that the 'big A' is not coming to bail them out of the financial burden of caring for older people. After all, the big 'A' has already been delayed for "generations" so to speak. lol
just saying!
