The renowned calligrapher of our country Su Juxian was still hale and hearty at the advanced age of one hundred, which is chanting to all. When summing up his own experiences on longevity, he laid special emphasis on observing the rules of the society and following the customs, letting thing take their own course. Even if there occur difficulties and distress, composure is required, and it is necessary to give rein to the situation, disregarding longevity. This is really a golden maxim for health preservation. Avoiding sexual strain is another very important key for preserving health and prolonging life.
Sexual strain means exhaustion due to intemperance in sexual life.
Sexual life to the moderate degree plays an important role in longevity. Our forefathers have accumulated rich experiences on this. Those at their fifties have sexual intercourse once twenty days while those at sixties totally refrain from it. That is why gentlemen take good care of essence but are cautious in sexual activities. Those who are still healthy and strong, however, should not suppress their sexual urge.
