What is [the first thing in life]? It is mental and physical health. The poor can not afford to treat the disease, where to get money? The rich have a disease really wrong, where to spend money? So the first thing in life is not to be sick (treatment of disease), less sick (treatment of disease plus prevention of aggravation of the disease), got sick to early treatment (early treatment is easy to heal, reduce various complications). Although the reason is simple, but the implementation is very difficult ah! In this regard, we must continue to learn the theory of disease prevention and fitness science and technology, even if it is a doctor should also learn, because you are not necessarily the omnipotent. Learned to adhere to the implementation of scientific theory at any time.
