Eating and drinking regularly, and living regularly are also the basic principles of health preservation. Reasonable diet, regular schedule, and avoiding unhealthy habits such as staying up late and overwork are all important factors in maintaining physical health. At the same time, 'not indulging in excessive sexual activity' also emphasizes the importance of avoiding excessive sexual activity, maintaining moderate and moderate sexual activity, in order to promote physical health.
By following the above principles, people can take care of themselves and live until they reach the age of one hundred before passing away. This is precisely the embodiment of the concept of the unity of heaven and human health advocated in the Yellow Emperor's Internal Classic, and it is also the health goal that we modern people should pursue. By studying this classic work, we can better understand natural laws, master the correct health preservation methods, and thus have a healthy and long life.
“食饮有节，起居有常”也是养生的基本原则。合理饮食，按时作息，避免熬夜、过度劳累等不良生活习惯，这些都是维持身体健康的重要因素。同时，“不妄作劳”也强调了避免过度房事的重要性，保持适度、有节制的性生活，以利于身体的健康。

通过遵循以上原则，人们可以颐养天年，活到一百岁才离开人世。这正是《黄帝内经》中所倡导的天人合一养生观念的体现，也是我们现代人应该追求的健康目标。通过学习这部经典之作，我们可以更好地了解自然规律，掌握正确的养生方法，从而拥有健康、长寿的生活。
