This book is not only informative, but hilarious in parts. Some bits are a little too scientific for people who are completely unfamiliar with that sort of things, but overall I would recommend this book to just about everyone who is interested in olfactory science.
A little too scientific for the everyday person, but a very interesting look into how scent affects us, how some people understand it better than others, and what type of thought goes into making a food/drink/perfume/whatever smell the way it does.
