That's very unfortunate for you, I'm sorry.
However, whether you get sick from your smoking or not is undoubtedly genetic.
The oldest woman in Britain died the other day, aged 114 years. She gave up smoking 30 years ago (at about 84 years), just in case it damaged her health. Evidently, it didn't!
Everyone who lives, dies. Some go fast, some go slow. Whether you smoke, eat fatty food, live in a smogy city,etc. We will all die, sooner or later.
I'm offended that the Govt and other busy-bodies try to perpetuate the myth that non-smokers all live to a ripe old age and all pass quitely in their sleep. And, somehow, use this as a justification for engaging in compulsory lifestyle control.
If anything was ever a more perfect example of blatant fascism, state-sponsored control over the personal behaviours of its citizens would have to fit the bill perfectly. The fact that they've gotten away with it for so long is what amazes me.
