Do your nostrils feel uncomfortable at times as there is "gold" (dirt) inside?All of us have to pick our nose to get rid of the "gold" in our nostrils.
How does it work?
The lining of our nostrils produces a sticky liquid called mucus. This mucus traps dust and germs in the air as we inhale. As the mucus dries up, it forms a gluey lining or a crusty layer inside the nostrils. In a nutshell, our nose helps to clean the air that enters our lungs.
