Let me talk about a little-known fact: in fact, the presence of body odour is \u00abnormal\u00bb, and the absence of body odour is \u00ababnormal.\u00bb<\/strong><\/p>\n <\/p>\n There are two types of sweat glands in the human body: 90% are eccrine glands, which are spread all over the body, wicking sweat is relatively thin and generally tasteless. The other is apocrine glands (also known as apocrine glands), which are only concentrated in the armpits, crotch, areola, and external auditory canal. Sweat also contains various proteins and fatty acids, which is related to body odour.<\/p>\n The secretions of the apocrine glands are not smelly, but after the secretions are decomposed by bacteria on the body surface, various unsaturated fatty acids are produced, which gives it a smell.<\/strong><\/p>\n The direct killer is bacteria, but how can there be no bacteria on the human body? So no matter how wrong you are with the apocrine glands, you still can’t escape the involvement. Who made you provide the murder weapon!<\/p>\n <\/p>\n Think about it: Everyone has apocrine glands, and everyone has bacteria. Why do only a few people have body odour?<\/strong><\/p>\n Those with body odour are not \u00aba few people\u00bb at all! In the beginning, our ancestors all had body odour. In animals, body odour plays a big role and is a pheromone for communication, so most animals have it. For people, body odour still plays a role in attracting the opposite sex, and men\u2019s body odour can cure menstrual irregularities when women smell it. Of course, after a person has a language, it is not so important to communicate with each other, but everyone has the remains of their ancestors.<\/p>\n It is said that before 2000 generations, we once had… (Here, 1994 words omitted) Great grandfathers walked out of tropical Africa and entered temperate Asia. The 538th base of the ABCC11 gene in the middle of chromosome 16 has a genetic mutation, resulting in a genetic mutation. Apocrine glands reduce secretion. This mutant gene occurred in East Asia. Because sweating is reduced and it is more adapted to the cold temperate climate, it has a genetic advantage. Therefore, after 40,000 years of natural selection, the mutant gene that removes body odour has become the majority in East Asia, and body odour has become a very small number…<\/p>\n Therefore, people without body odour are all descendants of that genetic mutation, and they are all mutants.<\/strong> (Do you feel like you are hanging like an X-men?) 95% of Chinese people are X-men, and over 99% of the population in the Central Plains of North China are X-men. The Chinese have escaped the fate of living with body odour all day long. You don’t know what a small probability this is.<\/p>\n People in other regions are not as lucky as the Chinese. In East Asia, Koreans are similar to Chinese, and 99% have no body odour. But only 84% of Japanese people do not have body odour, and 16% have body odour! There is one out of six people. Think about it. This is not the worst, not in East Asia, it would be even worse! Only 30% of the natives in Oceania do not have body odour, and only 10% of the white people do not have body odour! Only 0.5% of blacks have no body odour! In other words, except for East Asians, almost everyone with crooked nuts has body odour!<\/strong> Take a look at the body odour gene distribution map below. The yellow one is the X-man type without body odour, and the blue one is the wild type with body odour. Except for the yellow land of East Asia, the rest of the world is full of body odour! There are far more people with body odour in the world than people without body odour!<\/p>\n1. Causes of body odour<\/h2>\n
