Yeah Lori, that is sad!
A close friend of mine, her mother passed away from emphysema last year. Nothing was wrong with her, except that she couldn't breath. She said she knew it was coming . . . one year she'd went and visited her and she said she could hear her wheezing when she breathed, the next they had her on oxygen in the evening (and during the day she still smoked) and the last year she was on oxygen full time (couldn't smoke).
My neighbor passed away about 1-1/2 yrs ago. VERY sweet lady, smoked and got cancer. She was also on oxygen at the end because she couldn't breath.
SOOO SAD!!! Makes you mad . . .
