In English:
While we collect various popular knowledge about technology, entertainment, health, etc., there may be some "cold knowledge" that we have never noticed. Today, we will take "watching out for cold knowledge" as the theme to learn about some knowledge points that we may have never heard of.
1. The head of a pig being cut off will feel extreme pain and consciousness
Perhaps we have never realized it, but humans and animals are similar in pain and consciousness. In the initial stage of slaughter, if animals cannot die instantly, they will experience extreme pain, just like pigs.
2. The evil Walmart once sold cotton candy flavored Gillette razor blades
In the competition of many products, some companies make crazy attempts to attract consumers. Walmart is one of them. They once tried to integrate grapefruit and cotton candy flavors into Gillette razor blades, but this attempt was not successful in the market.
3. The lifespan of an adult dragonfly is only one month
Perhaps when we see a dragonfly, it means that their life has already completed a long journey. Generally speaking, the lifespan of adult dragonflies does not exceed one month. In this short period, they have to complete all the reproductive behaviors such as mating and laying eggs.
4. Cats' brains are better suited for tactical thinking
The intelligence of various pets varies greatly. Dogs are often loved for their intelligence, but cats' intelligence may be overlooked by the public. Studies have found that the way the cat's brain is constructed is more suitable for tactical thinking and deliberate thinking. This may be because of their long hunting and survival journey that gave them this way of thinking.
5. There is a "fishing season with explosives" in New Jersey
As a state full of surprises and wonders, New Jersey has many seasons that people cannot comprehend. The craziest one should be the "fishing season," which allows fishermen to use explosives to catch fish, of course, the purpose is to make it easier for fishermen to catch crabs and bluefish.
6. The fastest animal in the world is not a cheetah, but a swift
The highly anticipated cheetah may not be the fastest animal in the world. It is only the fastest animal on land, and the flying animals are much faster than cheetahs. The fastest animal in the world is the swift, which can fly at a speed of 120 kilometers per hour.
7. Human saliva contains some weak analgesics
We produce saliva every day, but we never thought that it actually contains some very small amount of analgesics called endorphins, which can relieve our discomfort when we feel pain.
Although these cold knowledge are not common, they tell us that we can look at things from various strange perspectives, and thus expand our thinking.
