Dotsie, were you surrounded by second hand smoke like I was? My dad smoked for many years, and died of complications/heart problems brought on by pulmonary fibrosis. Our family is actually part of a medical study at Duke University on pulmonary fibrosis, since so many members of my dad's family had/have the problem.

I hope I can avoid that, it's a horrible way to live your last months, gasping for breath.
