Your nose is the first indicator if you are about to die

It is our human nature to believe death in our minds, and imagining death is associated with seeing dead animals, humans, birds, and flies. So what’s the connection between all of this, but we haven’t really thought about it before? Going.

According to current research, the human nose cannot be classified into any specific category, but is capable of detecting a variety of odors that come into contact with them. Like an odor caused by a chemical called putrescine. It’s a chemical produced when the body begins to break down, and the only thing you need to be aware of is the smell from the animal’s years of toxic behavior. Evolution and these reactions are believed to have occurred at least 420 million years ago.

It is believed that animals react to the smell of putrescine as a sense of danger in two different ways: the reaction is that a predator is nearby, and the second is a life-threatening reaction, so instinct tells them to run.

Scientists conducted 4 different experiments on humans with a mixture of putrescine, water, and ammonia, just to confirm that human reactions and behaviors are no different from animal reactions and behaviors.

vigilance

In the first experiment in which participants were tested on the smell of putrescine, they were exposed to its smell and their alertness was tested. The results showed that participants exposed to the smell of putrescine had significantly higher alertness than those exposed to ammonia or water.
The scientists conducted exactly the second experiment, testing a group of unsuspecting people who were offered tasks to rate odors, disgust, and familiarity. The researchers wanted to see how the group responded to the scent and how quickly the participants moved 80 meters away. People who smelled putrescine tended to move away from the area more quickly, suggesting that the odor induces a strong escape pattern.

In another experiment, immediately after exposing the group to the smell of putrescine, the researchers asked the participants to complete the stem with the word.

The results showed that the smell of putrescine led the group to the word stem sum, all of which were related to the words escape and escape. Even the scent became sharper when using tense language.

defensive and hostile

This was the last trial in which the participants were exposed to a thick odor that they could not detect. In this experiment, they were presented with a research text and their task was to evaluate the author.
