Hi, my name is OB and I'm going to tell you about second hand smoke and the dangers of this. Second hand smoke is sometimes more worrisome than smoking itself. So be careful around children of the 90's if you smoke. I was a victim of second hand smoke. I had pneumonia when I was 3 years old. If your going to smoke be careful around kids. Its stupid that kids are getting sick from an adult's mistake. So if I were you, I 'd stop all together. Be careful. Choose not to smoke.
