Why Do We Breathe? By Jennifer Kenny

---

¹     Did you know that you will probably breathe in and out about 50 MILLION times in your life? Breathing means life for everyone. You have to breathe all the time. You would die if you didn't breathe. Do you know what's so amazing, though? You don't have to think about breathing. You just do it!
 
²     A baby breathes about 40 times a minute. A child breathes about 30 times a minute. An active adult breathes about 25 times a minute. Finally, a resting adult breathes about 15 times a minute.
 
³     You take in about one cup of air during each breath while you are resting. If you were doing something more active, though, like running, you would take in about six cups of air.
