A research reveals your body knows when death is near, and it all starts in the nose

Despite years of research and the advance of techology, there are some things about human’s body that still remain a mystery for doctors and researchers. Knowing how complex our bodies are, this doesn’t really come as a surprise. c “We do not know why we like (or dislike) someone’s smell, and we’re usually not aware of how scent influences our emotions, preferences, and attitudes,” Wisman and Shira explain. “It is hard to think of a scent as frightening,” other researchers claim. However, scents do make people more vigilant of their surroundings. Sex pheromones, which are defined as odors produced by either males or females, that stimulate one or more behavioral reactions in the opposite sex, bringing the males and females together for the purpose of mating are just another example of the effect of scent at humans. “Putrescine signals a different type of message than pheromones, but people’s responses to putrescine (avoidance and hostility) do seem indeed to be the opposite of responses to many sexual pheromones,” researchers explain. At the same time, the researchers explain that humans are not aware o the odor and don’t consciously associate it with death or fear.
