Many dangerous diseases are carried by bacteria - tiny organisms that can get into the body and multiply inside it. Bacteria breed in unhygienic environments, but soap can be used to keep our surroundings and bodies clean and healthy, keeping bacteria at bay. This book tells the story of how soap was invented, and its impact on our quality of life. You Wouldn't Want to Live Without Soap! is part of a brand-new science and technology strand within the internationally acclaimed You Wouldn't Want to Be series, created and designed by David Salariya.
