A new definition of health.

A new concept of health is presented. A third dimension called optimal health-fitness (euexia(*)) has been added to the conventional concept of normal health. The new concept is based on a different set of health-fitness standards which were derived from studies of population groups with exceptional physical vigor, exceptionally long and vigorous life span, and/or exceptional freedom from cardiovascular and degenerative diseases. A national plan for implementing euexia is proposed.
