After Watching ' Mom', I Realized: The Decline of the Elderly is Due to the Spoiling of Their Children
We're always like this, waiting until we're sick to appreciate life.
We only realize we need our own lives when we fall out with our children.
There's a question on Zhihu: What do elderly people fear most?

Young people say they fear loneliness, middle-aged people say they fear their children not being filial.
Young people often talk about the loneliness and solitude of the elderly until the elderly themselves speak up, and many people only understand then.
Even though people are old, they're still useless.

Elderly people fear being abandoned by society and fear simply waiting to die.
Even though longevity is impossible, people still try to grasp something. As people get older, they become increasingly selfish, which isn't really selfishness.
Elderly people are easily spoiled by their children, and they also easily lecture you on your age and act stubbornly.

The elderly aren't actually becoming bad; they're more resisting the rapid changes in the world.
Just like children can be spoiled by their parents, Old Age and Wisdom – it's easy to understand, difficult to practice.
