If you only face a white wall at home every day, the boredom of life will naturally affect your positive attitude.
Old people who live alone should not shut themselves in the house. They should do more things they like every day to enrich their lives. Now that the network is so developed, the society is getting better and better. If they don't like contact with people, there are also courses and online courses for the elderly online. Choose according to your hobbies, like to learn musical instruments, like to learn painting, and if you sing well, you can learn vocal lessons from professional teachers. Don't limit yourself, open your heart to everything.
Many old people have worked hard all their lives and know the hardships of making money, so they live frugally. Especially in their old age, they have to protect their daily needs and save a reserve for future medical care, so they live a tight life.
So, don't save money for the sake of saving money. First of all, protect your health, and don't deduct the expenses for diet or physical examination. Saving money is not to spend, but to spend, so that we don't have to live too hard. If our bodies are free now, our future life will be smoother.
