I did read once that smokers do the health and welfare systems a favour by dying early.
...The same could be said about many other "lifestyle choices" like smoking and illicit drugs etc. Unfortunately that is yet to happen and everyone pays.
No one should be forced to take the Vax, but you should sign a wavier to say you will cover your own medical expenses, both public and private. I don't see why the rest of should pay for your choice.
I could be wrong, but I'd heard of numerous occasions (in Oz) where Dr's refused to undertake certain high cost procedures unless the patient quit smoking. Maybe its high risk?
My parents are life long smokers, now 75, both seem to holding up well, and while they don't tell me much, I see early signs of potential bigger issues on every visit. That and the fact they looked very old 20 years ago. I fairly certain my dad having watched his father die after 5 years with dementia at 93 would rather go out the door with a smoking induced life limiting disease than allow himself to be in the same situation. His mother lasted until 103 (last year), she was god until last 1.5 years, mother nature is at times very cruel by not taking people when its time.
Meanwhile a guy I knew we went camping with him to Cape York in 2003, he was also a life longer smoker. Seemed fine during the trip, being an ex truckie and smoker was able to light a fire quickly as the rest of our group didn't smoke. However he was around mid 60's and 6mth on return he went down hill real fast over a matter of weeks and went into hospital not knowing if he'd come out and if he did on a O2 bottle.
Dr told him straight, keep sticking those in your mouth and you have no use for services. He stopped smoking instantly, released from hospital. Then had 12 years of happy life after that, not needing O, but took a while to walk long distances and got slower with time (yes Emphysema (spelling)). Last few years was more house bound and i think O2. Died around 80 a couple years back. He always told me he'd wish he's wised up at least 10 years before, but you make your own life choices.
I think he was probably one of the lucky ones, much better than what I've seen with Lung cancer. Although some just have a heart attack and die.
