Earwax and boogers!

"Earwax and boogers come from different places, but they're equally gross. This book explores why the body makes these icky, sticky substances and what it means when you find more than usual hanging around your ears and nose. Whether it means someone is getting sick or they just haven't taken a bath in a few days, this book explores good hygiene while also explaining the scientific reasons behind these important body processes"--Provided by the publisher.
