Anytime I hear of that kind of lung problem, excluding cystic fibrosis, smoking, allergies or asthma, I ask about cement dust, chemicals and wood sawdust (especially walnut and other tree species which have poisonous sap) and petrochemical refining.
Our lungs are incredibly beautiful, from a respiratory view, almost as wondrous as a leaf that makes oxygen and food with sunlight, water and CO2.
If either a leaf or a lung gets thick or sticky dust, the performance is reduced.

Take care of your lungs folks! Nothing but clean air should go in, nothing but used air should go out.
