Almost all of us know that smoking is bad for health.  But a smoker doesn't know it or doesn't want to understand it.  They don't want to accept the complex and difficult disease that they can get.  If you explain to smokers, they will explain to you on the contrary, those who are non-smokers are not affected by complex diseases?  Do they die?  I will say one thing about them, they eat in happiness and in sadness and in joy and in pain.  Usually, once young people get addicted to smoking due to peer pressure, they cannot quit it later.  Many years of consumption cause it to take a terrible shape.
