What a great post, Eve. Very well said.
I have a few things to add to the talk re lung cancer and smoking.
First, many people who die of lung cancer (like my sister) have it only because the first cancer in their body metastisizes (sp?) to another area. Usually when cancer metastisizes, it goes to the brain, the lungs, or the liver. If that's the case, then the lung cancer they have is in no way related to smoking.
Second, I have a friend who is the head of a very large hospital, and he says there is absolutely no empirical evidence to show that second-hand smoke is related to lung cancer. I've never done any research on this, so please don't bash me for saying it. But the man who said this is probably the brightest man I've ever known and, if he says it, I believe him. But our society has literally demonized smoking and smokers to the point that it's ludicrous. I think drug dealers are treated with more respect than smokers in our society, and when you can make that statement with a straight face, something is definitely wrong.
Personally, I don't think that smoking causes lung cancer. If it did, everyone who smoked would get it, and that's definitely not the case. I don't think they yet know what causes most cancers, including lung cancer, and Dana Reeves' recent death clearly illustrates there are many unknown factors that cause it. I hope one day they discover what causes all cancers... but until that day comes, demonizing a person because they smoke is not going to help find the real answers.
