I volunteered to serve food to the workers at Ground Zero after 9/11. There were dogs trained to find living people. The people who worked with the dogs became worried because the day after day of not finding anyone was beginning to depress the animals. So the people took turns hiding in the rubble so that every now and then a dog could find one of them to be able to carry on.
