Our nose helps our brain to figure out what foods we are eating, smells trigger memories, and also emotions. Our brain can differentiate between smells. It can trigger a nauseated feeling if there is something you do not like, or even stimulate hunger. Everyone's sense of smell is different, what smells good to one person may be unappetizing to another. When a person thinks about a food they enjoy their brain triggers the memory of how it smells, looks, and tastes. For example the smell of chocolate can cause people to have experience joy just from the aroma. People know the smell of family members, different types of wine, and also coffee. Certain places have a particular scent to it which makes it recognizable in the future. Below is a video on how the temperature can affect our sense of smell.
