Acharya Vagbhatta has aptly chosen the name of the chapter, one must have the desire to live longer only then one wisely chooses the do's and don'ts to lead a healthy life which Ayurveda advices.
One must understand that health is not merely absence of a disease Health is defined as a normal state of all physiological activities and a pleasant state of the sense organs, mind and the self.
