All that are posting advice on the subject are so correct that it is bad for your health but like everything else there are exceptions to the rule. There are those that seem to be able to smoke all their lives and live a long and healthy one but unfortunatly I am one of the many that it ended up making me sick from smoking but my brother who is twelve years my senior still smokes and I think it would kill him if he gave it up. My other brother never smoked in his life and karked it before he turned 60 so go figure that one out. Smoking does all that they say it does in fast tracking most to the grave but for some giving up would kill them from stress. Human beings are individuals and as such have different needs so be careful in advising the minority into doing something that could not only shorten their lives but also make them miserable for the remaining days on terra firma. Nothing bloody worse than an ex smoker (I know I am one).
As an aside to this topic why are we becoming used to peer pressure to make us all so bloody uniformingly and boring human beings without a trace of the old diversity and adventurous nature that we started out in this life with. No wonder those in power treat us like sheep.
That's the way the mop flops.
