Health is one of the greatest life values of a person. But, unlike material values, we are not used to preserving them wisely, much less spending them carefully. Often we simply don't see the need for it. It cannot be said, of course, that all people do not understand the importance of their health and do not value it. Most of us realize the value of our health when it is seriously threatened or lost to some extent. Only then does the desire to cure the disease and become healthy arise.
