1. Around 20,000 liters of air pass through the average adult’s nose every single day.

2. Humans have about 12 million olfactory receptor cells, but that number decreases with age.

3. The nose contributes to how we perceive taste.

7. Humans can detect more than 10,000 scents.
Your nose has approximately 400 types of scent receptors that can detect around 1 trillion different odors.

8. Your nose is connected to your memory. 
Our sense of smell is connected connected to the limbic system, which is the part of the brain thought to be responsible for the attribution of emotions to events. This is what causes certain smells to trigger memories.
