I think that if a person is unmarried for life and has no children, he or she can live a very happy life in old age. The situation of being childless and unmarried all one's life may well be forced, but it may also be voluntary, and the ways of how to live well in old age should be different for people in different situations. Some people may not find a partner because of insufficient conditions, while others choose to live alone because they have not met a psychological partner. I think that if you want to live a good old age, even if it is a lonely old age, you have to enrich yourself.
Some people may feel that people like this who are unmarried for life and have no children may have a very bad old age. Because you don't have anyone around to take care of you. There is an old saying that raising children to prevent old age raises children. Raising children does not necessarily prevent old age because it is also possible that children are unfilial. But there are people who say that children are the guarantee for parents in nursing homes, so if you have relatives or children who come to see you often, then the caregivers won't dare to do anything to you because they know that you have a family. Of course, if you don't have children, it doesn't mean that you will not be able to live well, you can also be very free and easy. We all know that children have the obligation to support their parents, so the elderly can get a pension from their children every year, which is mainly related to the children's ability and filial piety. No children of the elderly will not have this expense, if the young saved a sum of money, then the old age life is still guaranteed, or have a stable job with a pension. But if they have nothing, they have to find ways to cut expenses. Like I remember an old man, she must have children, but a long time to live alone, the old man is not there, although it looks very lonely, but not as bitter as we look at the outsiders. A person also has a person's way of life, no children, you can become a bit friendly, this way you can become a popular old people. If you stay with children for a long time, your mind will be much younger. This way old age will also be more enjoyable.
There is a home for the elderly near my home, and then after some major repairs from the public nursing home into a fee-paying nursing home, the original old people have been resettled to other nursing homes, because of the higher fees and some of the reasons why it has not yet opened. I still remember how those old people lived. Their lives were more regular and their diets were taken care of by specialized staff. If they are not too old to walk, they can go out for a walk or even do some small jobs. Like that kind of healthier, the elderly will live more happy, on the degree of freedom is also quite high, but like that kind of more serious disease, or too old elderly people will live more unfortunate, because the whole home seems to be only a caregiver, that will not be taken care of too comprehensively.
To live a good old age, whether or not you are married and raising children, first of all, don't spend all your money when you are young and remember to save. It's best to take out a pension insurance policy or a job with a pension. After you have the security of life, you can do what you want to do, and since you are not attached to anything, you can go farther and see the world. Or join some social groups, participate in activities to make their senior life more colorful.
