“In the past, people practiced the Tao, the Way of Life. They understood the principle of balance as represented by the transformations of the energies of the universe. They formulated exercises to promote energy flow to harmonize themselves within the universe. They ate a balanced diet at regular times, arose and retired at regular hours, avoided over stressing their bodies and minds, and refrained from overindulgence of all kinds. They maintained well-being of body and mind; thus, it is not surprising that they lived over one hundred years.“These days, people have changed their way of life. They drink wine as though it were water, indulge excessively in destructive activities, drain their jing – the body’s essence that is stored in the Kidneys – and deplete their qi. They do not know the secret of conserving their energy and vitality. Seeking emotional excitement and momentary pleasures, people disregard the natural rhythm of the universe. They fail to regulate their lifestyle and diet, and sleep improperly. So it is not surprising that they look old at fifty and die soon after.”
