First of all, if you're a smoker, I'm not saying there's anything wrong with you. It's your decision. I'm just trying to look at the facts here. Also, with this incident I'm about to share, I wonder if I have communication skill problems that I need to work on? We've all had our experiences with opinions about smoking. There was a woman at work earlier who'd always say, "I need to smoke. I need to take a (work) break," and she would start freaking out. So out of a sense of caring for my fellow human beings, I told her statistically smoking is one of the leading external risk factors for death in the U.S., and that it is estimated to be a major risk involved in around 18% of deaths. I even explained I found that in scientific peer-review journals, not that she knows what those are. So check this out, she laughed at me and said that statistics are made up. I told her they keep on saying on the news that heart disease is the leading cause of death, cancer is the next, and smoking is a "major risk factor" for the leading causes of death. I decided to figure things out for myself (critical thinking) and found out that just like you get a birth certificate, when you die you get a death certificate. The U.S. government health agency, Centers for Disease Control, and the American Medical Association even confirm that heart disease and cancer are the two leading causes of death. Although they don't keep track of whether you actually die from smoking, the way they come up with these estimates don't sound made up. Consider this, most who hit the bucket because of heart attacks under the age of 40 are smokers. Consider this, a little less than 90% of those who meet the grim reaper because of lung cancer are smokers. There are also other results for many of the other leading causes of death. So that's how they form a "best estimate". She again laughed at me and that statistics are made up. She said that you can also die from sharks. I told her, "Maybe a land shark. LOL. Let me think here, don't less than 10 people die from sharks every year?" She started laughing. Why was she accusing me of not using critical thinking? Given all the evidence I can find from the American Medical Association and the U.S. Centers for Disease Control, it sounds like the best explanation is smoking is a risk factor? Since I looked at an actual scientific peer-review journal article and printed it off, why is it made up? I mean seriously, pumping your lungs full of the crap that's contained within those fumes?
