     Neatness and personal cleanness have been around for ages and have become an important part of everyone's

daily routine. You might think that all modern societies would have the same neatness and personal cleanness

practices. After all, doesn't everybody take baths? Most people do recognize the need for cleanness, which is

the basis for health. Neatness practices include all the little things people do to make themselves look their best,

such as combing their hair and putting on makeup. However, while most modern people agree that these things

are important, people in different cultures take care of themselves in different ways.

     There used to be an old joke in America that people should take a bath once a week, whether they need one

or not. In fact, though, Americans generally take a bath or more commonly, a shower every day. But in contrast

to some cultures, most Americans get their shower in the morning so that they can start the day frcsh.

Americans are known for having very sensitive noses. In America, body smell is socially unacceptable. For that

reason, Americans consider it a must to use special lotion (浴液) to prevent the smell. Ladies often add a touch

of perfume. Men may spray on after-shave cream or manly-smelling perfume.

     Some of the cultural varieties in neatness practices result from physical differences between races. Whereas

many Asian men have little facial hair, Westerners have a lot. As a result, most American men spend some time

each day shaving or tidying their facial hair to keep it nice. American women, on the other hand, generally prefer

not to be hairy at all.

     Americans put great value on both neatness and personal cleanness. For some people, taking care of

themselves has become almost a religion. As the old saying goes, "Cleanness is next to godliness." Whether or

not being clean and neat-looking brings one closer to God, it certainly at least brings one closer to others.

Americans look down on people who don't take care of themselves, or who "let themselves go."
