Subject: Letter about the bad effect of smoking.

Dear Russel,
It is a long since I heard from you. Your silence pains me much. It will be a pleasure for me if you write to me time to time. It shocked me greatly when I learn that you have become a chain smoker. You are quite sensible and learned. So, I think you could realize the harmful effect of smoking. It damages our lungs day by day and loses his longevity. It causes many fatal diseases like cancer, heart attack, bronchitis etc. it also harms the nerves. Damages the brain and spoils the character. In another sense, it can be said that smoking is as bad as committing suicide. Please do not any injustice to yourself. I shall be highly glad if you give up this bad habit without delay.

Wishing you best of luck
Rakhi
