The difference between health and health preservation is too great. Health refers to your physical condition, which is an objective fact, and health preservation is an act, an idea and a practice! Health is not necessarily due to health preservation, and health preservation is not necessarily health. Some wrong health-keeping methods and concepts can not bring you health, nor can they keep you healthy, and may even be counterproductive. If you don't keep healthy, everything will go with the flow. As long as there are not too many serious bad habits, it may not be worse than those who deliberately maintain health every day. Therefore, health and health preservation are two different things, and there is no necessary connection between them. Even if you keep in good health, you should keep in good health rationally.
