Let's thank our lungs for 6 million breaths a year

Although we all know that without our lungs we would not be able to breathe and live, few people look up interesting facts about this vital organ. For example, did you know that the surface of our lungs is large enough to cover an entire tennis court? In fact, our lungs are such an amazing organ that they can "breathe" 7,500 liters of air per day. And since November is the Lung Awareness Month, join our challenge and let's dedicate these 30 days to them together!
