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

It is in our human nature to believe in death in our minds, and the way we imagine death is also related to seeing a dead animal, human, bird, or fly. So what’s the connection between them all, but we haven’t really thought about it before? Going.

According to current research, the human nose is able to detect a variety of smells that cannot be classified into any specific category but nevertheless react to them. 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 the only thing you need to be aware of is the smell as a result of the animal’s harmful behavior over the years. Evolution and these responses are thought to have evolved at least 420 million years ago.

It is believed that animals react to the scent of putrescine as a sense of danger through two different techniques: the reaction that a predator is nearby, and the second that it is in danger of life, so their instinct tells them to run.

Scientists designed 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 animal reactions and behavior.


The first experiment, in which participants were tested on the smell of putrescine, was exposed to its smell and tested their vigilance. The results showed that participants exposed to the scent of putrescine showed significantly higher alertness than those exposed to ammonia and water.
The researchers conducted exactly the second test in which they tested a group of unsuspecting people, who were offered work to assess smell, that is, intensity, disgust, and familiarity. The researchers wanted to see the group’s reaction to the smells and how quickly the participants moved away over a distance of 80 meters. Those who smell the putrescine tend to get away from the site faster, indicating that the scent elicits a strong escape pattern.

In another experiment, immediately after the group was exposed to the scent of putrescine, the researchers asked participants to complete the stem with the word.

The results showed that the scent of putrescine led the group to the word sum of stems, all of which are associated with escape and other associations with the word escape. The scent also spiked for the use of tense words.

defensive and hostile

The last experiment was in which participants were exposed to a creamy scent they were unable to detect. In this experiment, they were shown a text of the study, and their task was to evaluate its author.
