What is health?
Health is a state of complete mental, physical and social well being.
Healthy and disease free
Although most of the people use both these terms in the same context,
there is a clear difference in being healthy and disease free.
While healthy means being mentally, physically and socially fit, disease-
free is a state of absence of any body discomfort.
A healthy person can be disease free but a disease free person cannot be
a healthy person.
