I had nothing to do at home, and then I went out to learn more about life and become a writer. When I was waiting for moxibustion at a moxibustion hall, I met a middle-aged man. Let’s just call him Uncle A. After Uncle A moxibustioned his injured and ailing knee joint, he was lying down and demonstrating abdominal exercises, such as aerial bicycles. Then he showed two Taekwondo moves, and then introduced to the boss lady which parts of the Taekwondo moves were exercised, the miraculous effects on fitness, etc. I talked to the landlady. As the conversation progressed, I learned that Uncle A is now living a leisurely and comfortable life. His hair is still black, and he looks fifty years old. He has maintained his figure very well after being thirty years old. He does not have the pot belly and fatigue that most men of that age have, but he looks rosy and full of energy. He often runs or walks briskly in parks or track and field fields, and often appears in square dance teams, so the uncles and aunts nearby know him, and he often rides mountain bikes with some like-minded people. people chatted. When I asked him about retiring at such a young age, I learned that I had not retired and had not worked for many years. Our family is in the village over there. We have two five- and six-story houses. Since they are close to the city, we live in the upper two floors ourselves, and the lower floors are renovated into single rooms and rented out. We find someone to manage and collect the rent every month. My wife and I just do what we want to do and travel. I like sports like Taekwondo. I also bought sports equipment at home and often hang out. The locals here, even the older ones, are quite familiar with it. .
