I gave up the effortless way. I developed a pain in my chest that wouldn't go away.
Well, not for three months, anyway. I've never needed a cigarette since.

However, the damage was done. The pain was some kind of abcess or ulcer or something like that inside my aorta, which medical opinion firmly blames on smoking, and 26 years later, suddenly, I can't walk far because there isn't enough blood getting to my legs. The surgeon reckons that, because of the likelihood of collateral damage, he'd rather do a quadruple by-pass on me!
Do I want to stop smoking? Done that. Now I want to stop everyone else doing it.
I watched a friend die of emphysema. That may be worse than cancer.
