I read an article regarding the long term effects of smoking and dealing with the issue of
whether the lungs would eventually clear up after you quit.

I suffer from COPD but never smoked. It was probably caused by exposure to die-
cutting sheets of fiberglass back in the late 1970's.

Hopefully you find this interesting.
