Dear WW: In the early days of WWII, the Brits had to organize bombshelters, and sent out a
questionaire with a lot a questions that had to be answered, and the forms returned, to be used
in making plans and assigning all residents of the city to a shelter near them.
One small area had seventy five percent of all women reporting that they had claustrophobia.
The woman who had passed out the forms was called in and asked what she had told these women
about claustrophbia. She replied she had told them it meant "fear of confinement."
