I don't want to sound insensitive, however most people with copd and similar dis-eases or labels have poor lifestyle habits and diets.  I was one of those in my 30s and started to have all kinds of problems.  I would be the first one to say there is a pill for that.  Now that I stay away from processed foods, corp/med products, excersize, meditation, get sun and other things I've never felt better.  These are more important the older one gets. IMHO, people who are weak need to be quarantined, not society as a whole.  Eat to live, don't live to eat.  Proper food is medicine
