YOUR NOSE IS THE FIRST INDICATOR IF YOU ARE NEARING DEATH

It is in our human nature to believe in death in the mind, and how we imagine death is also related to the sight of a dead animal, person, bird, or fly. So, what’s the connection between them all, but we haven’t thought about it before? Smell.

According to current research, the human nose is capable of sensing a variety of odors that cannot be categorized in any particular category, but which nonetheless respond to them. Like the smell created by a chemical known as putrescine. It is a chemical that is produced by the body when it starts to decompose, and there is a small problem to be aware of, which is that the smell is the result of the animal’s malicious behavior over many years of evolution, and it is believed that these reactions have evolved over the course of evolution. 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: a reaction to the presence of a predator nearby, and a second reaction to the fact that their life is in danger, so their instinct tells them to run.

The scientists did 4 different experiments on humans with a mixture of putrescine, water and ammonia, just to prove that human reactions and behavior are no different from those of animals.

vigilance

The first experiment, in which participants were tested specifically for the smell of putrescine, was exposed to its smell and tested their vigilance. The results showed that participants exposed to the smell of putrescine showed significantly more alertness than those exposed to ammonia and water.

escape behavior

The researchers conducted exactly the second test, in which they tested a group of unsuspecting people who were offered a job assessing the smell, namely intensity, disgust and familiarity. The researchers wanted to see the group’s reaction to smells and how quickly the participants moved away to a distance of 80 meters. Those who smelled putrescine tend to move out much faster, proving that the smell provokes a strong motive for flight.

In another experiment, immediately after a group was exposed to the smell of putrescine, the researchers gave the participants the task of completing the stem with a word.

The results showed that the smell of putrescine led the group to a total number of word stems, all of which were associated with escape and other associations with the word escape. Aroma has also evolved into the use of drawling words.

Protective and hostile

In the latest experiment, participants were exposed to a smell so strong they couldn’t detect it. In this experiment, they were shown a text for a study whose task was to evaluate its author.

They were unable to identify the exact smell of putrescine, and the participants were defensive and hostile towards the author. It also demonstrated that unconscious exposure to the smell elicited defensive behavior in the participants.
