Children ask a lot of strange questions, and these books have the answers! This time it’s Dr Kaveh Rashidi answering a range of questions asked by children about the body. Because why do we have blood in our bodies? How do our ears work? Why do old people die? And can doctors really fix everyone who gets sick?

Why don’t tongues grow hair? is educational, easy to understand and humorously illustrated, and a perfect conversation starter about the body for children aged 6–9.

The entire series is illustrated by Leonard Furuberg, who has a playful and accessible style reminiscent of Pixar/Disney animation.
