This book about the science of smells takes a funky subject and makes it fascinating --- and hilarious! It starts with the basics, from the reason why things stink to how our sense of smell works (hint: it has to do with the six million scent receptors way up inside our noses). Then come some specifics such as how and why smells are closely linked to memories, descriptions of some of the stinkiest stinks on Earth and information about the chemicals that smells are made of.
