SENSE OF SMELL
The nose is centrally located on the human face; it is a perennial in fashion and cosmetics, and indispensable for those of us who wear eyeglasses. In social and cultural life and literature, too, the nose is a familiar feature--one need look no further than the many proverbs, sayings, nicknames, and terms of abuse that relate to this striking part of the face.
The nose also forms the external section of the olfactory organ, however, and as such it does not receive the attention it deserves. For example, too few people are aware that breathing through the nose is vital to both physical and mental health. This method of breathing ensures that the air is to some extent warmed and filtered, and in addition it creates the correct pressure in the arteries in the chest cavity. Finally, one smells more when one breathes through the nose, which generally benefits mood and memory.
