Features: Health is the foundation for people to engage in all kinds of endeavors. So, where does health come from? The World Health Organization proposes that an individual's health and longevity depend on 60% on themselves, 15% on genetic factors, 10% on social factors, 8% on medical conditions, and 7% on the influence of climatic and environmental factors. In other words, 60% of the factors contributing to health and longevity rely on establishing a scientifically sound and reasonable lifestyle. Everyone can have health, but health requires the accumulation of daily efforts in one's life. As long as you contribute to your health every day, you will become a healthy person. The book "Health Is So Simple" introduces methods to enhance the human immune system from multiple perspectives, including diet, exercise, and medicine, reflecting the concept of holistic health encompassing fitness, health, wisdom, joy, beauty, and virtue. The content is rich, easy to understand, and practical for daily application, making it highly suitable for those who are concerned about their self-health. Therefore, I recommend it as a preface.
