Take a big breath. Hold it in. Where did the air go? Why do we need it? There are so many questions to answer.
I breathe to stay alive. Without air, my body would stop working in only a few minutes. Oops! Don't forget to let that air out.
It's really amazing! I breathe about 20 times every minute. Each breath is about a cupful of air. This means 20 cups every minute! If I'm running around it could be as much as a hundred cups of air that goes in and out of my lungs. Imagine how much air I use in one day! It's no wonder I want to breathe clean air.
