Please don’t make the mistake of looking down at people you see in public using portable oxygen devices, and smugly thinking “they got what they deserved” because their poor health is based on their poor lifestyle — choosing to smoke. This judgmental attitude is wrong for many reasons, one of which is that are those us, INCLUDING ME, with Stage 4 (also sometimes called “end stage”) COPD, WHO HAVE NEVER SMOKED AND HAVE LIVED A HEALTHY LIFESTYLE (and I will leave the lack-of-morality-and-compassion reasons out of my post in this instance).
