Who does a person depend on when he is old?

It is very heavy to mention the topic of providing for the aged. When people are old, some rely on their children, some rely on themselves, some rely on nursing homes, and some rely on their wives. I think it's best to support the elderly by yourself. It's better to have your own pension, and don't ask others for money. It is best to have a healthy body to take care of yourself and not disturb the children. Children have their own families, their own jobs, heavy family burdens and great work pressure. Some children don't even have jobs, and they have problems with their own sources of life. How do they take care of their parents? Nursing homes are not good either, after all, they are not as comfortable and convenient as their own homes. Relying on his wife is one thing, but his wife is also an octogenarian who can't keep up with her physical strength and needs someone to take care of her. Therefore, we advise our retired old people to keep healthy, always know how to support themselves and not worry about their children. Dancing, playing cards, swimming and singing at the age of 70 and 80 are the best. After all, you have to rely on yourself to support the elderly. Don't drag a sick body when you are old, which will not only hurt yourself but also bring trouble to others. Advise all retired people in the world to pursue a healthy body and strive to support the elderly on their own.
