From a sociological perspective, social norms are informal understandings that govern the behavior of members of a society. Social psychology recognizes smaller group units, such as a team or an office, may also endorse norms separate or in addition to cultural or societal expectations.
Sewer Odors in Bathroom. DEAR TIM: We recently have begun to notice a sewer odor from only one of the three bathrooms in our house. It might be the toilet, but it's hard to tell. The smell is not constant and some times it is very strong. Everything in the house drains fine, including the toilet with the odor.
But the good news is that there are relatively simple ways to take care of halitosis. Much of the time, bad breath comes from the gases produced by bacteria accumulating in the mouth, on the gums, teeth and tongue, said Dr. Jeffrey Spiegel, an otolaryngologist in Boston. Many of these gases contain sulfur, which gives them their stinky smell.
