Traveling with cystic fibrosis can take a little extra planning, but there’s no reason why you can’t explore the country, as Beau Rich shows. 

Breathing occurs 15-25 times a minute, and the average person will inhale 10,000 liters of air each day. Sound simple? It isn’t. The act of breathing is incredibly complex and requires the brain, lungs, heart and diaphragm to work in harmony with each other in order to deliver oxygen-rich blood to the entire body.

All of this happens without most of us even thinking about it — unless we suffer from a lung disease that makes breathing difficult, like cystic fibrosis.
