Book excerpt: Noses are wonderful things. They help us breathe. They are lined with mucous and hairs called cilia, which trap germs and tiny particles that can make us sick. They generate quarts (litres) of snot. They let us smell flowers and freshly baked foods. They also warn us of dangers from fires, rotten food or last week’s gym bag. Let’s see how much you know about noses. Can you answer these questions? How much snot does your nose make each day? How fast is a sneeze? What does a runny nose mean? Who can smell better, women or men? How many different smells can your nose detect? Find out more about your nose and amaze your family and friends with these fun facts. Ages 8 and up.
