The Smell of Feelings

While all of our senses have jobs that help us to interpret the outside world, it is typically just assumed that smell is mostly used in the identification of food, trash, and places. However, studies have shown that the sense of smell can interpret feelings as well as identify people. Every human has a distinct odor, much like fingerprints. This is why working K-9s are able to track people for far distances. A person's sweat is also linked to their emotions, and the smell of the person's sweat based on that emotion can cause another person to also feel that emotion. This is actually an unconscious reaction, and most humans do not realize that the emotion change is coming from the smell we pick up from another person.
