I am sure someone with more medical background will answer, but from my EMT training I know that. COPD is chronic obstructive pulminary disease. It is caused by inhalation of solids, smoke etc. years ago it was called black lung disease because it was so common amongst coal miners. It causes a lot of problems with breathing, most people with the condition develope a very prononced shape to the chest due to the extra effort they need to inhale. Unfortunately there are only treatments to help with the symptoms we cannot repair damaged lung.
I don't have it, but worry sometimes. All those years smoking and working inside tanks with the silica dust so thick you couldn't see two feet, and the metal dust etc, and now I find I really enjoy this new hobby with coal dust and smoke and more metal and abrasive dust. I guess it's time I got something better than a cheapy dust mask.
Prayers to you Paw Paw.
