Life lies in exercise and health lies in health.

What is health? If you are destined to come to the west beach of Qinhuangdao in the early morning of winter, you will definitely see an 85-year-old gentleman swimming in the sea in winter. His name is Zhang Jingbo and he was born in 1922. At the age of 85, in the eyes of ordinary people, Mr. Zhang is still laughing, healthy and happy. The old gentleman has a saying, which reveals profound philosophy in his humor: "From 1957 to 1979, my right-wing career for more than 20 years has unexpectedly transformed my body, although I have not' transformed' my thoughts". Right-wing life-extremely hard physical and mental suffering, it is this suffering that inspires the vitality of the elderly. From this we can think: life lies in exercise, so what is health? Can we say that health lies in suffering? 1979 after the old man was rehabilitated, he worked as an office and went to work, but in less than three years, he developed diabetes. In order to recover, the old man had to rediscover his hardships ―― he practiced for nine days in winter and three days in summer. He swims in the sea every day as long as it is not a thunderstorm. What is health? Health lies in suffering. Some people may curse when they hear this, but this is the reality. Cui Yongyuan of CCTV can't sleep, and medicine can't do anything about it. But the hard long March made him sleep soundly every day. What do you mean by health? Why are the founding kings of past dynasties physically and mentally healthy, and their children and grandchildren are full of misery? However, most of their children and grandchildren died short-lived and had few children. Why, lack of suffering! Speaking of which, how do we treat ourselves and eat delicious food? Winter and summer air conditioning? What can I do, go on road trip? Seek medical treatment for serious illness and minor illness? Such people are everywhere in real life, but the end result is that delicacies make the gastrointestinal tract overworked, overnourished and obese. Air conditioning makes people catch a cold when they leave the house, catch a cold when they leave the house, and be hospitalized when the weather changes. Thousands of people are light, and tens of thousands are heavy. Money is still a trivial matter, and the body and mind suffer immeasurable pain! Countless facts tell us that health lies in hardship: climbers, great physical exertion produces a strong heart and a beautiful body; Swimmers, the cold sea water stimulates their adaptation to various climates. They don't know where the hospital door is open. They don't know whether the pills are round or flat. Over time, the cliff without road is no longer pain, but strong wine; Cold sea water is no longer fear, but indispensable dew-tribulation is not all pain, but more sweetness, tribulation is life, and tribulation is health! Friend, we really should think about it. Are food, air conditioning, cars and medicine really necessary and indispensable? Is the luxury house that supports our life a kind of enjoyment or a kind of suffering? Or the middle way between the two? If so, are we enjoying too much happiness and suffering too little now? If we want to balance, should we increase the pain as soon as possible?
