Those Two Air Bags
Your lungs are a magical place. The magic is gas exchange. Oxygen goes into the bloodstream and carbon dioxide is kicked out. Without lungs, we’d suffocate. Only organisms that are small and/or wet enough can “breathe” through their skin. For big, thick humans, lungs are essential to our existence. Make sure to take care of yours by exercising often and reducing the amount of pollution that you breathe in. Our lung necklace makes a great gift to yourself or you can buy it for fresh air enthusiasts, high altitude athletes, endurance athletes, and starry-eyed pre-med students.
