5 things I learned from _What the Nose Knows: The Science of Smell in Everyday Life_

_What the Nose Knows: The Science of Smell in Everyday Life_ (2008) by Avery Gilbert

The author's description of himself demonstrates that he is definitely someone who gets to play in the overlap between science and media studies:
"...I'm a sensory psychologist, trained in evolutionary theory, animal behavior, and neuroscience. I'm a rational, evidence-based guy working in the most frothy, fashion-driven, marketing-heavy business outside of Hollywood....
The new science of smell is making us rethink everything from wine tasting to Smell-O-Vision. So it's time for a fresh look at odor perception and how it plays out in popular culture."
