Cancer seems a high price to pay for an innocuous-looking habit. You get into smoking and you are robbed of the last 25 years of your life. Some cocky souls will say, 'Ah yes, but they are the worst 25 years.' Nobody feels like that in a cancer ward. There are no cocky souls in a cancer ward. But there's a lot of pain, not just of the excruciating physical kind that they shoot you full of morphine to smother. There are a lot of tears. All round. It is hard to say goodbye to the people you love. And it's scary. Cancer wards have a way of knocking the cockiness out of you. And for what? Another cigarette?
