1, the word "asshole" comes from Mongolian.
Once upon a time, the Mongols in the north of China lived a nomadic life in groups, and it was convenient to set up yurts to settle down when they met water plants. During the day, men go out to graze, leaving only old people or women to guard the tent. At this time, the little boys who stayed at home for various reasons, in order to find beautiful girls to love, ran around and sneaked into girls' tents.
Sometimes, when young people meet strict old people, the old people will angrily scold "you are an asshole again" and "the asshole is coming again". The young man got bored and hurried out. Over time, the word "f * * king" has evolved into swearing words, which has nothing to do with the original "sneaking into the tent".
No one knows who invented the fire hydrant.
Because the patent book was destroyed by the fire. 1836, a fire broke out in the Washington Patent Office where the patent files of fire hydrants were stored, and most of the patent files stored in the office were destroyed by the fire.
Including the patent files of fire hydrants, so no one knows who invented the fire hydrants until now. Isn't it ironic that the fire hydrant specially used for fire fighting failed to keep its own patent file?
3. Hens can change their sex automatically.
When there is no rooster in a flock of chickens, the hen may become a rooster. This phenomenon is called inversion, which is caused by many factors such as animal's physiological state, external environment, hormone treatment and so on. But females will have two organs that make germ cells, one will develop into ovaries and the other will be undifferentiated. For some reasons, such as there is no male in a flock of chickens, some hens will have "ovarian atrophy" and another set of organs will differentiate into testicles, so hens will become roosters.
Inversion is not a chicken patent. Some fish, such as Monopterus albus, can be hermaphroditic and spontaneously inverted under normal circumstances. Androgyny has two types of organs, and their development can alternate, that is, "male first, then female" or "female first, then male".
When addressing a couple or lovers, people always put the boy's name first.
The study found that when addressing a couple or lover, people used to put the boy's name first. At the same time, if you match the names of imaginary gay couples, you will find that the more masculine and masculine names are in the front.
Feminine or feminine names come later. Have you ever made a similar discovery? Even if you support gender equality and gender mainstreaming, do you have similar habits?
5, high IQ prefers to be alone?
Do you prefer to be alone or get together with friends? Research shows that people with higher IQ are less willing to be with friends. Spending too much time with friends often makes them feel very unhappy. This may be because people with high IQ need to reduce social interaction in order to focus on long-term goals and maintain more intellectual stimulation.
