Generally speaking, life is infinite, and there is no end to human growth; Personally, life is limited, and everyone can only live his own life. So young people should work hard and grow up. When they are no longer young, health care is the main task.
People over 500 years old should listen to their inner voice and act immediately if they want to do something. Don't put it off until the future, and don't hesitate, such as traveling, just leave if you want, starting with your bags. On the other hand, when you don't want to do something, don't embarrass yourself. Why bother when you are old? Everything is casual, casual.
