The plot of the story was as follows: In the past, the lifespan of humans and animals was 30 years. One day, a young farmer decided not to borrow his life from the cow and monkey, but to do everything he could to extend his own life. He realized that if everyone could live as long as he did, the world would be a better place. Therefore, he began to look for various ways to extend his lifespan. He studied medical knowledge, tried various treatments, and even started practicing yoga and meditation. He tried his best to maintain a healthy lifestyle. He ate healthy food every day and exercised appropriately to avoid all unhealthy habits. After a long period of hard work, the farmer finally realized that his lifespan had been greatly extended. He was no longer the young man who only had 30 years to live, but an older man. The farmer was happy to realize that his life had been extended, but he also found that his life had become more lonely and boring. He no longer had the time and energy to pursue love and friendship because he had too much time to spend. Finally, the farmer realized that although his life had been extended, his life had become even more empty and helpless. He began to regret the things he had done in the past. He regretted not having the time to enjoy life and spend time with his family and friends. This story tells us that although longevity is a wonderful thing, we should cherish our time and pursue what we really want. Even if we have a long life, we shouldn't waste our lives. Instead, we should use them to do what we really want to do, so that our lives will be more fulfilling and meaningful.
