A gay lobby group in the Netherlands is launching a Quality Mark scheme for resthome operators so they can check whether they are providing a good service to their "pink pensioner" residents.
Apparently gay residents are not as well regarded in resthomes by the other residents as social status is determined by the number of visitors a resident gets, such as by children and grandchildren, the report says (in Dutch only, unfortunately).
I would be all for gay-only resthomes and this may well become commercially feasible in the future. Belgium is already getting one. A few hunky nurses to help you bathe, feed and entertain you sounds like a fabulous way to ease out of this life even if it costs 60 to 90 euros a day.
