Some people actually do quit smoking once they're diagnosed with copd. My dad is one of those people. He's 69 will 70 in December this year.
He was diagnosed with copd I believe 10 years ago and has not smoked since. He started smoking when he was 18 and I remember him smoking when I was a kid.
He'd always have a cigarette in his mouth. As well as his mom. His mom used to smoke too. She died at age 70 when I was 9 years old.
So my dad had smoked for around 42 years and he quit smoking cold turkey. And never touched a cigarette again.
So far he's doing good right now. I used to smoke myself because I wanted to imitate my dad and thought smoking was good.
But when he was diagnosed with copd I decided to quit smoking and glad I did.
