There are four major factors for a long and healthy life: 20% genetic factors, 30% environmental factors, 40% lifestyle, and 10% medical conditions. We can clearly see that 70% of them can be improved and controlled by us. In other words, these 70% are the main factors that induce cancer. In addition to the familiar atmosphere and various kinds of pollution, we should also pay attention to the state of mind: a pleasant working environment. A harmonious family atmosphere, strong self-regulation and adaptability. Bad lifestyle: smoking, drinking and gambling, often being in the pandemonium of mahjong parlors, day and night internet cafes, unhealthy eating habits (fried, pickled, rotten), all these can be changed. The body needs exercise. It needs to be cultivated both inside and outside. The phase is born from the heart!
