The nose is an important body part for breathing and smelling. We can smell pleasant scents and the delicious aroma of food.

With a good sense of smell, one can become a chef or a perfume expert. People around the world tend to like similar scents and dislike similar odors.

The human sense of smell can distinguish about 1 trillion different odors. There are even professions that specialize in using the sense of smell, such as wine tasters and perfumers.

Recently, the importance of smell has been highlighted as loss of smell has become known as a major symptom of COVID-19. In psychology, research on "olfactory memory," where specific scents stimulate memories and emotions, is also actively underway.
