Okay, it's goodies I need to address my comments to (sorry again, bypassblade, I made a mistake blasting you).
So, goodies, I just want to say, to your response that if smoking decided to take you tomorrow, you wouldn't care--unfortunately, death caused by smoking is rarely quick, unless you have a fatal heart attack. And they are still painful, even though death may be quick. More likely, it would be a slow and agonizingly painful death.
That you want to keep smoking and drinking is your prerogative; you have the right to do so, but you're kidding yourself if you think you won't someday regret it. Me mum died from emphysema due to heavy smoking, and the last 6 months of her life, she was totally bedridden, couldn't talk at all or breathe very well and she suffered terribly. She also lost an eye and was nearly blind in the other eye, due to the damage caused by smoking.
But let me ask you this--being as heavy a smoker as you say you are--are you not coughing sometimes? Wheezing and finding it hard to catch your breath when you exert yourself? If you say you are not, I'm afraid I would find it hard to believe you.
Good luck.
