Brilliant, but sad. The bus stop, in front of the Benrath Senior Centre in the western city of Düsseldorf, is an exact replica of a standard stop, with one small difference: buses never stop there. The purpose is to "trap" Alzheimer patients that wander away from the hospital. "They know the green and yellow bus sign and remember that waiting there means they will go home.” The result is that errant patients now wait for their trip home at the bus stop, before quickly forgetting why they were there in the first place."
