Smell

You breathe about 23,000 times every day.

Every time you do it, whether you like it or not, you smell. The air around you is full of molecules that you can’t see with the naked eye. In one breath, they enter your interior so many molecules like stars you see in the sky.

Smell, like the rest of our senses, gives us information about our surroundings. It can also evoke vivid memories or generate emotional responses.
