Thank you Mark. Mainly, COPD is exasperated by the fur, hair, feather and other dust particles in the air when tying flies. Also arthritis and shoulder problems don't help. Cleaning out the fly fishing room has been an experience. I've given 2 pontoons and 2 fat cat tubes to grandkids. A bunch of fly rods, reels, line and flies have gone to those who want them. No one wanted the tying stuff so selling it.
