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 seeing a dead animal, person, bird, or fly. So, what is the connection between them all, but we haven’t thought about it before? going.

According to current research, the human nose is capable of sensing a variety of odors that cannot be classified into any particular category, but which nonetheless respond to. Like the smell from a chemical known as putrescine. It is a chemical produced by the body when it begins to decompose, and there is a small problem to be aware of, which is that the smell is the result of the insidious behavior of the animal 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.

Animals are thought to react to the smell of putrescine as a sense of danger in two different ways: one reaction to the presence of a predator nearby, and another reaction to the fact that their lives are in danger, so their instinct tells them to run.

Scientists conducted 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 specifically tested for the smell of putrescine, was exposed to its scent and their alertness tested. The results showed that participants exposed to the putrescine scent showed significantly greater alertness than those exposed to ammonia and water.

escape behaviour

The researchers performed exactly the second test, testing a group of unsuspecting subjects who were offered a job evaluating the odor, namely intensity, disgust, and familiarity. The researchers wanted to see how the group reacted to the scents and how quickly the participants moved 80 meters away. Those who smelled putrescine tended to move more quickly, proving that the scent triggers a strong drive 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 a word.

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

Protective and hostile

In the final experiment, participants were exposed to a scent so strong they could not detect it. In this experiment, they were shown a text of a study whose task was to evaluate its author.

They could not identify the exact smell of putrescine, and the participants were defensive and hostile towards the author. It also showed that unconscious exposure to the odor elicited defensive behavior in the participants.
