As we all know,in manyEnglish-speaking countries, halitosis口臭is one of the great taboos.We all know Americans like to chewgum.Therefore,you’d better keep your mouth always fresh in communication, especially in business activities.
Human olfactory response to odors affect the refraction of human culture. Different people in different cultures have different
feelings to odor which is emitted by the human body For example, sheep smell is unacceptable for many Chinese people; lots of Chinese like eating the dumplings with meat and leeks,but many westerns do not enjoy this smell.

The smell is caused by a chemical substance,but people are born with the smell.
It is determined by many factors, such as habits, eating habits, ethnic, physiological changes, hygiene, health, and climate etc.
Research shows that pleasant scents generally have a positive effect on mood and memory while unpleasant chemicals showed a negative effect (Chen and Haviland-Jones, 1999). The use of pleasant smells, like perfumes and colognes, may have positive impacts on people, makingthem feel happier and may elicit the remembrance of good memories. That’s why Westerners like wearing
主流科学家早先将人类的嗅觉归于“锁和钥匙”的假说。这个想法是，每一个进入我们的鼻子 的气味分子都有一个特定的形状，相互吻合的特定受体——就像锁和钥匙一样——使我们能够 感知，例如感知焦咖啡的刺鼻气味。但是，假设留下了一些没有回答的问题。其一，它没有解 释，为什么我们能够依靠几百种的受体来感知数以万计的不同气味。它也没有解释为什么有着 非常相似的形状的气味分子会给我们带来千差万别的气味，例如带给我们伏特加气味和臭鸡蛋 气味的分子有着几乎相同的形状
Sometimes Smell Overload happens when a large quantity of odors in in one place or one when one smell is just extremely overpowering. Smell Adaption tipically occours when a indicidual has arepeated contact with a certain smell. For
Mainstream researchers have long attributed our sense of smell to a "lock and key" hypothesis. The idea is that every odor molecule that enters our nose has a specific shape that fits a specific receptor—like a key fits a lock—allowing us to detect, say, the acrid aroma of burnt coffee. But the hypothesis leaves some questions unanswered. For one, it doesn't explain, why we can detect tens of thousands of odors with only a few hundred smell receptors. It also doesn't explain why odor molecules with very similar shapes give us such different smells; for instance, the molecules that gives us the smell of vodka and rotten eggs are almost identical.
Smell is one of the most basic modes of communication.It also plays a role in olfactory communication, can spread racial, cultural habits and family characteristics related information to help people identify the smell of their own body odor and properly treat others. In a word, it is very necessary for us to pay more attention to Olfactics.
how does the sense of smell work?
Smell receptors in the innermost parts of the nose bond to gas molecules from the air. The receptors then send electrical signals to the olfactory bulb, which signals the orbitofrontal cortex, where the firing pattern reveals to the rest of the brain what smells so nice (or bad) out there. Most receptors (though not all, according to preliminary research in Don Leopold's lab) are arrayed in two dime-sized patches, one per nostril. The first gene for a smell receptor was discovered as recently as 1991,by a team from Columbia.

Scientists have long known that people perceive scents. “Everybody’s olfactory world is a unique, private world,” says Andreas Keller, a geneticist at the Rockefeller University.

In social situations, Arab people always stay closed. The distance between the two talk sides is nearly enough to smell each other's body odor在社交场合中，
