Suddenly, I felt that having more babies could not alleviate the problem of providing for the elderly. Grandpa has 5 children, each of whom has achieved a small career, but when his mother calls in the morning, he learns that all 5 children are playing back and forth to support, accompany and visit. Even if the old man said that he wanted to see everyone more in the last few years. I don't know if it's like this in my family, or if it's like this in the world.
