Sir,

It is a privilege to receive an invitation from your prestigious school, to speak on the importance of physical health .The effort of your school authority, to make the students aware of the importance of health, is commendable. I will definitely come, for such a noble cause, on 28 Feb. 2013 at 11 a.m. I will try to make my presentation enjoyable through projector slides and flash cards.

Thank you very much.

Yours faithfully,

Dr. Gandhi
