How to face death?

One day, someone suddenly asked me: You have lived a long time, and you are as happy and harmonious as everyone all day, have you never considered the future? I looked into his loyal eyes, and I also deeply overshadowed the truth of his question, so I answered frankly: I long to live, but I am not reluctant. Even if you stick to it, it won't help, right? Man lives, grows old, dies of illness, and no one can ever avoid or escape from this problem. Since the history of human civilization for thousands of years, which dynasty and generation of emperors and generals, princes and ministers, and heads of state generals and marshals are not all the same as all ordinary people, saying that if they are gone, they will be gone? The old decay may suddenly disappear one day, quite a natural reason, there is nothing to fuss about. Not just me, but in another 100 years, maybe a little more, everyone in the world, including newborn babies, will be replaced by their children and grandchildren. So for death anyone should face it calmly, there is nothing to fear! I'm older and closer to that day, but I'm not afraid. As long as I am not tormented by illness before I die, life can take care of itself and can live with dignity, of course, I am willing to accept. But if it's the opposite, then I'd rather choose death. Do not live hard, suffer.
