The WHO Definition for Health

As health-care providers, we aim to prevent well people from becoming sick people, and fortunately, greater awareness of preventive health has helped make that goal a reality. Public health education about wellness-inducing behaviors, such as good nutrition, regular exercise, smoking cessation, weight control, vaccination, and cancer screening, have contributed to the wellness of the general population. And yet, while medical technology is advancing at a rapid-fire pace and our understanding of what prevents disease continues to grow, our society is increasingly obese, hypertensive, and diabetic, suffering from heart attacks, strokes, and cancers, or doped up on drugs for anxiety, depression, and bipolar disorder. (Location 1493)

A better definition of health includes the thriving of the individual in a holistic sense

Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
