Why do women have body odor? What is the cause of body odor?
A group of people have to spend a lot of money to increase their investment in perfume in order to cover up their strong smell. Which group do you think this is? That's right. It's the fox stink group.
Is the body odor group rare? In fact, this phenomenon is more common than we think, people with body odor are also very common, there is no body odor is variation. Don't laugh adult toys for men , it's absolutely true.
Where does body odor come from?
First of all, let's talk about the production of body odor.
As we all know, there are eccrine glands and apocrine glands in human sweat glands. Sweat glands are concentrated in some parts of the body, such as armpits and crotch, and the rest are eccrine glands, accounting for about 90% of the total sweat glands.
Generally speaking, the sweat of eccrine glands is relatively thin big dildo , most of them are water, there is no taste, so regardless of body odor. In addition to moisture, sweat from sweat glands often contains proteins and fatty acids. It doesn't matter if it's a little more. Because these things are tasteless. However, don't forget that there are still many bacteria on the surface of the human body. The secretions of apocrine glands provide conditions for bacteria to grow, and when they are broken down by bacteria, they produce various unsaturated fatty acids, which gives them a bad smell.
In theory, everyone has bacteria, so everyone should have body odor. It was true thousands of years ago. The ancestors of the earth had the so-called body odor. You can even imagine the spectacle of them together. The smell could be miles away.
The refreshing gene born out of nowhere
About 2000 generations ago, there was a low probability event. When human ancestors came out of tropical Africa and entered subtropical Asia, there was a mutation in the gene responsible for sweat gland secretion, resulting in a decrease in sweat gland secretion. This means that the growth conditions of smelly bacteria become worse and the body becomes refreshed. And this gene mutation mainly occurs in East Asia, accounting for 95% of the Chinese. Since then, because the refreshing gene has been passed on from generation to generation, now most Chinese people do not have body odor. The refreshing gene frees us from the fate of being surrounded by stench and becomes the biggest beneficiary of genetic mutations. From this point of view, the number of mutants in China is much larger than that of normal people without gene mutation.
In other countries lockthecock , Koreans are as lucky as we are. They also carry 90% of the refreshing genes, so not many people have body odor. But, relatively speaking dildo shop , the Japanese are not so lucky. Only 84% of them have refreshing genes. In other words, 16% of the Japanese still retain the original taste of their ancestors.
And foreigners who are farther than the Japanese in East Asia. 90% of Caucasians do not have refreshing genes, and they have a great taste in summer. When you walk up to whites or blacks, you often smell pungent perfume, which is a clever way for them to hide the original smell. Therefore, it is not so much to like perfume as to cover up the smell of the body. So far, most whites and blacks still have the same smell.
Different nationalities have different tastes, which is a very interesting thing. We can use it to study racial changes, and it is correct. For example, most Native American Indians do not have body odor, indicating that they are from Asia. The percentage of Japanese people carrying refreshing genes is different from that of other ethnic groups, suggesting that they have different origins.
At that time, it was normal to have body odor, and those without body odor would be laughed at by others. However, with the passage of time, the situation gradually changed.
