Everything You Didn't Want to Know About What Makes You Scratch. Everybody gets itchy, and every kid will love this title that scratches the itch to know more and about the history, anatomy, botany, biology behind it. Perfect for fans of Grossology books looking for something more substantive and dynamic. You can feel it coming on—that terrible, tortuous ITCH. As irritating as an itch is, it is also your body’s way of sending you a message you can’t miss, like you’ve brushed up against poison ivy or lice have taken up residence in your hair. None of which you’d know without that telltale itch! And there are so many things that make us itch—from fungus to fleas, mosquitoes to nettles, poison ivy to tarantulas! Combining history, anatomy, laugh-out-loud illustrations, and even tips to avoid—and soothe—the itch, Anita Sanchez and Gilbert Ford take readers on an intriguing (and sometimes disgusting) look into what makes you scratch.
