It is in our human nature to believe in death in our minds, and the way we represent death is also linked to seeing a dead animal, human, bird, or fly. So what is the connection between them all, but we haven’t thought about it before? he goes.
According to current research, the human nose is capable of detecting a wide variety of odors, which cannot be classified into any specific category, but it reacts accordingly. Like the smell developed by a chemical known as putrescine. It’s a chemical that the body produces when it starts to break down, and one thing you need to be aware of, the smell is the result of the animal’s aggressive behavior over the years. Evolution and these responses are believed to have evolved at least 420 million years ago.
It is believed that animals react to the smell of putrescine as a sense of danger through two different techniques: the reaction that a predator is near, and the second that they are in danger of life, so their instinct tells them to run.
Scientists created 4 different experiments on humans using a mixture of putrescine, water and ammonia, only to prove that human reactions and behavior are no different from those of animals.
vigilance
The first experiment, in which participants were tested to know exactly what putrescine smelled upon exposure to its scent and their alertness was tested. The results showed that participants exposed to the putrescine scent showed significantly higher alertness than those exposed to ammonia and water.
escape behavior
The researchers conducted a second blanket test in which they tested a group of unsuspecting subjects who were given a job rating the odor in terms of intensity, disgust, and affinity. The researchers wanted to see how the group reacted to the odors and how quickly the participants moved away over a distance of 80 meters. However, those who smelled putrescine tended to move away from the site more quickly, proving that the scent triggers a strong urge to fly.
In another experiment, immediately after the group was exposed to the smell of putrescine, the researchers gave the participants the task of completing the stem with the word.
The results showed that the smell of putrescine led the group to the sum of the stem words, all of which were associated with escape and other associations with the word escape. The smell also increased when stringed words were used.
Defensiveness and hostility
The last experiment was in which participants were exposed to a cream scent they could not detect. In this experiment, they were shown a study text, and the task was to evaluate its author.
