Wellness is an active process of becoming aware of and making choices toward a healthy and fulfilling life.

It is "a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity" - World Health Organization
and
"a conscious, self-directed and evolving process of achieving full potential." - The National Wellness Institute.

Maintaining your health and wellness is the most important thing you can do to add quality years to your life.
