We might not always think about how wonderful it is to taste food. Or to hear music.
But some people are missing one of their senses. Blindness is when a person cannot see. Deafness is when a person cannot hear. The loss of smell is called anosmia.
Our sense of smell helps us enjoy good things. Imagine cookies baking. Think of flowers in bloom. Smell also keeps us safe. It tells us to stay away from spoiled food or polluted air.
Anosmia has a number of causes. Illness is one. But it can be treated.
