Fluency Ex. #4

We know smoking is bad for human health. I am one of the people who smoke, and when I smoke I know these cigarettes will hurt me. But sometimes I think smoking is good for me, because I get angry too fast and smoking helps me to calm down. Also, when I read something or try to understand something, I think when I smoke I feel that I understand more than before. For example, when I study I feel a headache, then I don't understand what I studied; smoking lets me repair and go again without the headache and I can understand what I read.
