That's true. In the traditional culture of China, immortals are pure. Without worldly desires, they cannot eat or drink. This is the so-called Buddhist health preservation, but it is a myth after all. We don't know whether there are immortals, but this living habit of immortals is really Buddhist health preservation, but we don't advocate it because we humans will die faster. Who can do without eating or drinking?
This is the first time that scientists have found evidence that the activities of the nervous system affect human life span. First of all, it is common sense that aging will affect the nervous system. Alzheimer's disease and other neurodegenerative diseases related to aging are evidence. Obviously, there are inextricably linked between nerves and aging, whether it is positive or negative. In order to confirm this view, researchers have done a lot of experiments, and finally proved that changing the excitability of nerves will really affect life span, prolong inhibition and shorten enhancement. So this is based on science.
Finally, I want to say that since scientists have proved that Buddhist health preservation is good for our lives, we should also pay attention to this aspect in our daily life, for example, don't be too excited and learn to control our interests. Only in this way can we live happier in our daily life.
