Before you read this book we think it would be a wise practice if we caution you that you will really laugh, and the laughter may not cease immediately, it may go on recurring periodically even when you have finished reading the book. However, this is a desirable deed as far as health is concerned. You know that laughing is healthy; we care about your well being, that is why we do all these. So we urge upon you to cooperate with us in this honorable task of laughing.
