Despite years of research, some aspects of the human body remain a mystery.
Recent studies suggest that humans may subconsciously sense when death is near.
When the body begins to decompose, it releases putrescine, a foul scent associated
with decay. Researchers Arnaud Wisman and Ilan Shira found that humans, like animals,
react to this odor by moving away, a response linked to survival instincts. Although
people are not consciously aware of the scent or its connection to death,
it triggers avoidance and vigilance, similar to responses to danger
