Observation 4/1

Have you ever thought about how truly bizarre the sense of smell is?

Imagine an alien without the sense of smell coming to our planet and learning about it. Using the same organ that we use to exchange oxygen and carbon dioxide, even humans (one of the weakest species on the planet when it comes to smell) can distinguish, from hundreds of yards away, what is in their vicinity. We can tell from upstairs if it is cookies or bread baking in the oven. We can identify if the goo on our shoe is dog shit or just dirt. We can tell the past of a complete stranger (if the man on the elevator hasn't showered in a few days) and even the future of someone we've never met (an overly-perfumed woman is waiting for a man to come meet her). We can smell if rain is coming and if a person has been in a smoky bar.

Our sense of smell is more impressive than we give it credit for.
