The book is guide for healthy living which will help anyone elongate his or her lifespan in this sinful world. The title of this treatise could therefore be "How to live longer" but nowadays because of the problems of survival in this precarious world, many prefer to go early. We know of course that a rational man will think twice before destroying his God given soul. For a Christian, this is out of the question because it is a mortal sin. The soul does not belong to mortals, it is God's property given to us with love. We are enjoined to keep it nourished and safe until we are called upon to return it by the Owner, the Lord and Landlord of the universe.
