What kind of feeling is psychology too old?

Being old in your heart shows that you are mature and sensible. This is a good thing. Don't worry about him. Even if you are old in your heart, you will still have a childlike innocence. It's just that you think more and more comprehensively when you do things, and your eyes are different from others. You may have been through too much. Please remember that experience is a valuable asset. Therefore, older people will appear more mature.
