“迺問於天師曰：余聞上古之人，春秋皆度百歲，而動作不衰；今時之人，年半百而動作皆衰者，時世異耶，人將失之耶？歧伯對曰：上古之人，其知道者，法於陰陽，和於術數，食飲有節，起居有常，不妄作勞，故能形與神俱，而盡終其天年，度百歲乃去。今時之人不然也，以酒為漿，以妄為常，醉以入房，以欲竭其精，以耗散其真，不知持滿，不時御神，務快其心，逆於生樂，起居無節，故半百而衰也。”


Yellow Emperor (Huangdi/黄帝) asked Qi Bo(岐伯): “I heard that people in ancient times could be over a hundred years old, and their movements did not show signs of aging, and they still maintained vitality.

They have a moderate diet, regular work and rest, and do not indulge in promiscuity or unbridled work, so they can be physically and mentally strong, coordinated and live to their natural age (a person naturally grows up while keeping all the organs of the body in a healthy state). Lifespan), people live to be a hundred years old before passing away; this is not the case with people nowadays. They drink wine as water, indulge in excessive sexual activities, and make abnormal life a habit. They have sex when drunk and indulge in sensuality and other behaviors, which will lead to ‌ Exhaustion of essence and dissipation of vital energy. ‌, unable to be satisfied (unrestrained indulgence), unable to control one's own will, only seeking subjective emotional momentary happiness, violating the objective joy of life, and having no rules in daily life, so he will age in half a hundred years.”
