1. Winter is the peak season for hemorrhoids, and the dry climate can exacerbate the condition. (Note: The last part about hot pot and chrysanthemum is unrelated and appears to be a separate, incomplete thought.)

2. Lactic acid bacteria drinks do not offer health benefits. Lactic acid bacteria drinks are simply beverages; the bacteria they contain cannot permanently reside in the gut, so drinking them doesn't actually provide any health benefits. Furthermore, these drinks often contain added sugar for better taste, which may actually pose more health risks.

3. Why do humans love alcohol? A study called "drunken monkeys" suggests that the human love of alcohol is genetic, because human ancestors had an innate craving for energy-rich foods.

4. Why do some people dislike cilantro? According to surveys, about one-seventh of the world's population dislikes the taste of cilantro, describing it as similar to soap. Research has found that SNP genetic variations play a role in the perception of cilantro's taste; people who dislike cilantro possess a specific gene called OR6A2. This gene is used to detect the unique aroma of cilantro. Therefore, disliking cilantro is not necessarily being a picky eater.

5. An experiment found that pigs can learn to recognize human faces through special learning or training, and stimulating the pig's visual system can enable the pig to form an unusually rich cognition.

Why do people like to drink alcohol?

6. In 2016, Chinese people consumed 12.34 million tons of chicken, ranking second in the world. This was only 30 million tons less than the United States, which is the country that loves chicken the most. However, the United States has a population of just over 300 million, so the per capita chicken consumption in the United States is far higher than that in China.

7. The calories from a cup of cola, a hamburger, and a bag of fries would require walking continuously for 7 hours to burn off.

8. The British Parliament once had a rule that members of parliament were not allowed to wear hats into the chamber, but were required to wear hats when speaking. PS: Many members of parliament entered the chamber bald, but wore a public hat provided by the chamber when speaking.

9. Japanese trains are among the most punctual in the world, with an error margin of no more than one minute. This punctuality is due not only to the Japanese people's strong sense of time but also to the fact that the stations are very close together, reflecting the country's small size.

10. Nursing homes are not a product of modern society. As early as the Tang Dynasty, a very complete elderly care system had already been established.

11. Elephants can hear sounds through their ears and feet. Using special fat pads on their feet called "digital cushions," elephants can hear sounds from other elephants many kilometers away that are below the range of human hearing. This helps them avoid danger and sense impending floods and predators.

12. In the animal kingdom, hunters typically have vertical pupils, while prey typically has horizontal pupils. This is because prey needs a wider field of vision to observe their surroundings and prevent being ambushed, while hunters need to focus their gaze on one spot and lock onto their target.

Knowledge sharing should be both interesting and useful.
