Is my body the same as everyone else's? What is inside my head? What makes me feel things? How many bones do I have? What is my funny bone? What is my skin for? How thick is my skin? What are goose bumps? How do I move? Why do strong people have big muscles? What is a cramp? Why do I breathe? Why do I get hiccups? What makes me sneeze? What does my heart do? What is blood for? How big is my heart? Why do I blink? Why can't I see in the dark? Why are ears such a funny shape? Why do I feel dizzy when I spin around? What is my nose for? What is my tongue for? Why do teeth fall out? Where does my food go? Why do I go to the bathroom? Why does my stomach rumble? Why do I have to sleep? What is sleepwalking? What is a dream? Why do I get sick sometimes? What are germs? Why do I need shots? Where do I come from? What is my belly button?
