Relative to our other senses, our sense of smell wins by far more than a nose! On average, we can hear around 20,000 different frequencies, and we can see and distinguish more than 16 million colors. But when it comes to the nose and our olfactory system, we can smell over 10 billion different scent ingredients! Yes, that’s right, 10 billion! This is one of the reasons why our sense of smell is the most powerful sense that we possess, combined with the fact that we can remember 35% of the things we smell versus 15% of what we see.
