Women ovulate about 400 times in their lifetime, and according to the 28-day menstrual cycle, they can ovulate 13 eggs 365 days a year, so the number of years they can ovulate in their lifetime is nearly 31 years. If we add one year of pregnancy without ovulation, the number of years we can have menstruation is 32 years, and if we have many children, it will be extended. In the old days, women menstruated late, after 14 years old, often 18 or 19 years old, so that women’s menstruation lasted roughly until the end of about 49 years old, which is the seventy-seven forty-nine period of the ancients. Due to the protective effect of estrogen, the incidence of coronary heart disease in women after the age of 60 years and gradually higher than in men, before the age of 55 years of coronary heart disease are called “early onset coronary heart disease”, generally have a family history. The reality is, one is the food hormones cause women to menstruate earlier, eight or nine years old menarche is not new, so that ovulation began many years earlier; two is the implementation of family planning, women pay less time for childbirth, and ovulation interval reduced; three is the status of Chinese women rose, women’s influence in society increased, the corresponding is the work pressure and load of women increased body load. As a result, women experience early menopause, even in their thirties, accompanied by an increased incidence of gynecological diseases such as breast cancer and cervical cancer, as well as an earlier onset of heart disease due to the lack of estrogen protection. And this is basically what is seen clinically. Tiankui is considered to be the birth of the innate essence stored in the kidneys, but it is not fixed and unchanging. It is also important to take care of the innate, which is the capital given by nature, and this capital gradually decreases with the aging of life, so if we pay attention to the regulation, we can keep the water flowing, otherwise the source will be depleted. The society should pay attention to food safety, improve the concept of fertility, regulate the emotions, and regulate the rational use of drugs.
