Always hard to know with science in the news but I thought that there was some good science that showed that even quitting late in life significantly reduced the risk of smoking related illnesses compared to those who did not stop. I thought that was quite interesting that even after say 30 years you could change the odds fairly dramatically.

I've seen that too something like "after an hour your blood pressure returns to normal. After a few days you can breathe easier..."

It's always good to quit but as with genetics people are different. A few rare cases where a person smokes until their 90s and never seems to be affected. But I'd say most people who smoke are not so lucky. Sure maybe in the short term and yes it's great for the ex-smoker and the people around them but late in life illnesses pile up and COPD is a big risk.

My dad smoked but quit around age 30 now he has two lung diseases: COPD and IPF. It's possible one or both are related to his work as an oiler on a ship. He was always around fumes, dust, paint, exhaust but his smoking probably had a lasting effect too.
