Everyone knows that Germany produces some of the world's greatest engineers but what isn't so well known is their accomplishments in tricking the senile. To combat the problem of Alzheimer's patients wandering off, some care facilities are installing fake bus stops to help corral patients. "It sounds funny but it helps, Our members are 84 years old on average. Their short-term memory hardly works, 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." said Franz-Josef Goebel, the chairman of a local care association called the "Old Lions." Errant patients now wait at the bus stop for their trip home. After sitting for awhile they forget why they are there in the first place and are brought back to the facility.
