Many problems are faced as you grow older such as loss of vision, taste, and hearing. A new study says the ability to smell the food also decreases as we age. Humans not only pick up aromas of food through their nose but also through their mouth while chewing. Retronasal smell is smelling the food behind the nose when food is chewed. In this process, the volatile molecules are released which then drift through the mouth to the back of the nose where odour gets detected. Unfortunately, this ability also decreases as you age.
