The sense of smell is more closely linked to our memories than any of our other senses. People with full olfactory function can think of full memories just by detecting a specific smell either intentionally or spontaneously upon coming across a scent by chance.
The strong link between our sense of smell and memories is similar to the link between smell and emotions. An article from Fifthsense.org explains that even the perfume industry is aware of this fact and creates scents in order to convey specific feelings and emotions in order to increase business. The sense of smell is so emotive that it is said to be a contributing factor in romantic relationships between two people. The article states that the act of kissing evolved from the original act of sniffing a partner to decide if they are a match. The power of smell is correlated to association and our body's natural inclination to link specific smells with our feelings, thoughts, and emotions at that specific time. This leads our brains to believe that a smell can cause us to feel a specific way, when in reality it is just an association to other factors.
It is interesting to think about the enormous impact that our sense of smell has on every aspect of our lives from physical to cognitive to even emotional. For more information visit the following link: http://www.fifthsense.org.uk/what_is_smell/psychology/

I thought this chapter was very interesting as well. We do not realize how much smell impacts our lives on a daily basis and we take it for granted. The link between smell and emotion was very interesting to read about and it makes a lot of sense. I can't imagine not being able to smell my loved ones. Like Karl says, people go through depression because they can longer smell their loved ones. I never realized how much smell impacted our relationships. Great post!
