I get what you are saying, but your sample size of two does not gibe with the rates for a larger population size. My grandmother, a lifelong smoker, had cardiology bills up the ying-yang. My grandfather didn't smoke, but was subjected to a LOT of second-hand smoke from Grandma. He had a couple of cardiac bypasses. They both lived into their 80's which I was sure happy about, but the Medicare folks probably not so much! There is a large group of people like my grandparents and not so many that just up and die quickly without expensive treatment and lingering morbidity.
And I know a lot of other non-smokers who have a lot of problems also.
This isn't about defending smoking. In fact Using tobacco products in any form is the hallmark of an idiot. I quit in 1976. Haven't missed it a bit.
My point, if I have to hammer it in, is that we are all going to die, and no matter how much we think we are going to be immortal, smoking or not smoking is more in line with choosing the mode of our demise. There is more to this matter than concern for health.
The anti smoking zealots are the same as the mothers against drunk driving zealots, who both by the way, have been pretty successful in meeting their goals. The number of people that smke toady has fallen drastically, and there has been a real dent in dui. Those "random" stops are yielding less arrests now, and in my area (college football and student town) the "random" stops were a real cash cow for a while. Now they might stop a few hundred people and net one or two.
But now we see weird stuff like "third hand smoke" or "impairment starts with the first drink". There is outrage over vaping, which you would think the zealots would embrace, because now the evil tobacco users aren't using tobacco, and not inhaling all that nasty stuff into their lungs - just nicotine. But people trying to quit with nicotine patches is okay? And one drink will turn you into a careening drunken killer on the highway.
Yet nicotine is not carcinogenic, and ethanol in proper amounts keeps the CV system clean and healthy. Note that either in large amounts is nasty bad for you.
More like a lot of people just need a target to bestow their hatred upon. They need something to hate. And there is a weird streak of puritanism in the ultimate goals of both parties - prohibition take 2.
In the end, my story is we are all gonna die, and just because we do what the "smart" people say you should do, doesn't meant you are going to live any longer than the stupid people who don't do as the smart ones demand.
