What if we didn't have snot and mucus? The insides of our bodies would be very dry, and we would find it hard to digest our food. We would also quickly become sick, because mucus protects us from dirt in the air that we breathe. But what exactly is this sticky, slimy stuff and why do we produce more of it when we have a cold? And what do animals like slugs and snails do with their mucus? You might find it a bit gross, but you wouldn't want to live without it! You Wouldn't Want to Live Without Snot! is part of a brand-new science and technology strand within the internationally acclaimed You Wouldn't Want to Be series. The clear, engaging text and humorous illustrations bring the subject to life and stimulate young readers' curiosity about the world around them.
