I’m now a little over 5 years into my vegas podcasting adventure, and in that time, i’ve completed well over 200 episodes – including bonus & special episodes. Back in the early days of the show, i covered some pretty interesting topics and had conversations with some pretty incredible guests. Unfortunately, a lot of those episodes are now buried deep in the podcast archives and the chances of new listeners discovering them are pretty low.

So, in order to save you from having to go digging for them, i’ve put together a feature i’m calling “From The Vault”, where I re-share what I consider to be some of the best content from the early days of the podcast.

And this time around, we’re going to talk about the science of smell…

If you’ve ever been to Las Vegas, you’re well aware of the unique scents of the various casinos & hotels up and down the strip. In fact, if you ask people what one of their favorite parts of going to Vegas is, they’ll often tell you, “it’s the smell inside the casinos” – and it seems everyone has their preferred casino scent. So much so that there are literally thousands of posts online from people asking how to either purchase or replicate their favorite casino scent.

But what’s the big deal about smell? Why is the “scent” of a casino so important that the companies that own them spend - literally - millions of dollars on the development and distribution of these so-called “signature scents”.

To get the answer, i turned to an expert…

Dr. Rachel Herz is a cognitive neuroscientist, a Ted-X speaker, published author, and a world-renowned expert on the psychological science of smell.

In addition, Dr. Herz has worked as a consultant for multiple international corporations on the development of fragrances & flavors – including the company first responsible for installing scent vaporizer systems in The Mirage back in 1991.

Dr. Herz and I discussed how the sense of smell works, the connection between scents and emotions & memory, how businesses use scent to affect customer behavior, and much more.

To learn more about the science and psychology of scent, visit Dr. Herz's website or follow her on Twitter. You can also pick up one of her books:

• "The Scent Of Desire: Discovering Our Enigmatic Sense Of Smell"
• "Why You Eat What You Eat: The Science Behind Our Relationship With Food"
• That's Disgusting: Unraveling The Mysteries Of Repulsion"
