WASHINGTON, Apr 05 (Reuters) - The average American spends about an hour in the bathroom every day, or two weeks a year, according to a recent survey. The National Association for Continence (NAFC), a group that studies the bathroom habits of the American people, found in its survey that the bathroom has in many cases become a haven where many find comfort and relief from life's stresses. The survey was conducted by Yankelovich Partners on behalf of the NAFC, and randomly polled 1,001 Americans in shopping malls nationwide. About half of the respondents said they read or pondered serious issues in the bathroom, while one third admitted to simply daydreaming, singing in the shower or even talking on the phone. One third of women said they talked to themselves or admired themselves in the bathroom, and 22% of men said they had made love there. The NAFC, however, said bathrooms are not spiritual sanctuaries for all Americans. "Toilet mapping", or the scouting out of bathrooms in unfamiliar locations in case of an unexpected call from nature, is not an uncommon behavior. According to the study, almost two-thirds of respondents said they scouted bathrooms at amusement parks or cinemas, and those older than 50 were more likely to do so. The survey was funded by a grant from Pharmacia Corporation, marketers of the overactive bladder treatment Detrol.
