Introduction | Task | Process | Evaluation | Conclusion


Whether you're wide awake while prepping for that big date or asleep during your most snooze-worthy afternoon class, you don't have to think about breathing. It's so important to life that it happens automatically. Each day you breathe about 25,000 times, and by the time you're 70 years old, you'll have taken at least 600 million breaths!

If you didn't breathe, you couldn't live. It's one of the most important functions your body performs!
