COPD is not a disease that can be cured, or even treated. You will die slowly, and without being able to breathe adequately. If you survive long enough to be placed under medical attention 24/7 you will then also likely have O2 therapy 24/7, which will dry out your nose and/or mouth for the remainder of your life.  At some point, your body won't even be able to expire enough air to keep excess CO2 from building up in your blood, causing many more symptoms. One of which is the carbonic drive to breathe being overwhelmed to the point of being unreliable. This then means that your entire respiratory rate is influenced by the oxygen drive instead. You will be poisoning not only your lungs, but also your blood, and connected directly to that, your kidneys.  There is a lot more though.  And if this was a rhetorical comment, hopefully someone else will find it helpful.
