I wrote some of the following on another post, but wanted to add 
something.. I'm 74 years old and have been smoking 1/2 to 1 pack per day for 54 
years. Although I had 
	no symptoms and felt great, my doctor 
ordered a Pulmonary Function Test (PFT) 6 years ago (2013) when I was 68 and it 
revealed Stage 2 Moderate COPD. I continued smoking and had another PFT 3 years 
ago (2016) at age 71
	. I didn't get the 
printed results, but doctor said I have about 70% lung function left. About a 
year ago I noticed
	 a cough after getting up in the morning, but no 
cough the rest of the day. Also recently started hearing crackles when I lie 
down on my right or left side for sleep. I never hear them during the day and 
I've never been on inhalers or oxygen. I'm in the middle of changing my primary 
doctor and will get in for a visit to evaluate my situation within a month.
I know I'm responsible for the damage to my lungs and regret it. I quit 
"cold turkey" twice in the past and I know I can do it again. But if I get to 
the point where I have to be on oxygen, I think I would take my own life as 
having the expense and inconvenience seems like a very 
	low quality of 
life
	. And I never want to become a burden to my family! I get the 
impression there are not many people on oxygen 24/7 as I 
	rarely see them 
out and about.. I never knew the lung damage was irreversible until recently. 
Assisted suicide is legal in my state and wonder if many COPD patients around 
the country take advantage of it??
