People in the same family often talk about a loved one who has d*ed. People often tell stories about what a person did before they d+ied, like saying goodbye, putting an end to difficult relationships, or even giving away treasured items. It looks like they might know something before anyone else.
But some people might say it’s just a chance, while others are sure that people know when they’re about to die. It’s normal to try to figure out why someone we care about di+ed or to try to picture what happened in their last moments. Scientists know that as soon as a person di+es, their body starts to break down.
Putrescine, for example, is a smell that comes from decay and is bad for your health. Researchers have found that people are unconsciously aware of this putrid smell. Not only that but when the smell is let out, it makes something happen right away.
Animals can smell each other’s scents, which makes them act in a certain way.
This is the same as feeling danger, whether it comes from a predator or another animal in their pack that is stronger and bigger.
A study by Arnaud Wisman from the University of Kent’s School of Psychology in Canterbury, UK, and Ilan Shira from the Department of Behavioral Sciences at Arkansas’ Tech University in Russellville, AK, found that animals and people might not be so different after all.
All species need to be able to smell chemical odours to stay alive. People can smell when they are in danger of dy+ing.
When a body breaks down, it gives off a chemical called putrescine.
It also serves as a danger sign. When people smell this scent, they do something both consciously and unconsciously. Putrescine, ammonia, and water were used in four different tests to see how people reacted.
One of the experiments involved putting out putrescine at a spot. As soon as people saw it, they left the area.
This response is the same as the “fight-or-flight” response.
When animals feel like they are in real danger, they can either fight the danger or run away from it. People act in the same way, the study showed.
Sweat is another smell that people respond to.
Separate studies have shown that when people’s sweat was taken when they were scared and left out for others to smell, it caused an unconscious startle response.
Wisman and Shira say, “We don’t know why we like (or dislike) someone’s smell, and we usually don’t know how scent affects our feelings, preferences, and attitudes.” The other two top researchers say, “It’s hard to think of a smell that would be scary.” People are more aware and careful when they smell these things.
When people see danger, their natural response is not to face it and fight.
People try to stay away from fights, whether they are vocal or physical. Most people choose to stay away from each other until they have no choice but to fight.
PUTRESCINE AND $EX-PHEROMONE MAY GIVE DIFFERENT RESPONSES, BUT THEY ARE BOTH BASED ON SMELL.
$ex pheromones are chemicals that the body gives off to attract a mate. Putrescine, on the other hand, is a signal that something is wrong. “Putrescine sends a different kind of message than pheromones,” say the researchers.
“However, people’s reactions to putrescine (avoidance and hostility) seem to be the opposite of how they react to many sexual pheromones.”
During the study, people didn’t know that the smell made them feel bad. Wisman and Shira admit that most people don’t know what putrescine is and don’t connect it with de+ath or fear.
