Fake bus stop keeps Alzheimer's patients from escaping - Boing Boing:
"A nursing home in Germany built an exact replica of a bus stop in front of the facility. The only difference is that buses never stop there.
“It sounds funny,” said Old Lions Chairman Franz-Josef Goebel, “but it helps. Our members are 84 years-old on average. Their short-term memory hardly works at all, but the long-term memory is still active. They know the green and yellow bus sign and remember that waiting there means they will go home...”
“We will approach them and say that the bus is coming later today and invite them in to the home for a coffee,” said Mr Neureither. “Five minutes later they have completely forgotten they wanted to leave.”"
