Smell has been on my radar for YEARS. It has been the topic of several deep conversations with one of the authors (Linda Heart) for whom I’ve edited. The sense of smell is fascinating — the science of the sense of smell! Odors detected by the nose travel direct to the olfactory nerves at the base of the brain, the limbic system (also the name of a band: www.youtube.com/watch?v=InYi3n7A6sY). There is still a lot to be discovered about the sense of smell — mark my words! And thank you for this post; I am going to be sniffing all day long today and probably tomorrow, too.
