Really? Then how come any of us are still alive?
You've probably breathed in several molecules of carcinogens from diesel fumes in the time you've spent reading this post.
And you're probably exposed to the carcinogenic effect of your wifi as we speak.
And every time you venture out in the sun, you're exposed to UV rays.
And if the building you work in is built from granite then you've probably breathed in a fair amount of radon gas.
I could go on, but I think you get the picture.
To be factual: Each of us is dying.
That is the one thing that is predictable with 100% certainty.
And to be physically factual: Each of us "has" cancer. That's right, everyone on the planet has cancer.
To be even more precise, several thousand events take place within the body of each of us that has the potential to develop further and to become malignant tumours.
Systems within us protect against those further developments to stop them progressing.
At some time, with some people, those systems either stop working [properly] or get overwhelmed and the response is inadequate.
With smoking it is the damage within the lungs that overwhelms the protective systems (lungs are one of the organs that have no repair ability), that and the massive amount of carcinogens that are input to the organ.
You can smoke if you like, nobody is stopping you. The government (and not just labour....no party has said they will revoke the legislation banning workplace smoking) has decided to be more proactive.....and to be fair, as I remember many people trying to get a cigarette out and light it as they drive along, I can see the reasoning behind banning smoking whilst driving. That and the reduced decision making ability caused by reduced blood oxygen levels and the "high" of a known narcotic drug.
Whether it is a good idea, or enforceable, is another thing.
One good thing about having to stand outside smoking [at work] [or at other peoples workplaces (pubs)] is that many smokers are giving up smoking. Or trying to.
And for mobile-use-whilst-driving......at the end of this
REPORT is a list of events that were attributed to mobile use while driving. At the very end is a [long] list of research papers on using a mobile while driving.
