I have also thought about this question from the physical and psychological aspects. If I have cancer, and it is incurable, I will give up all treatment measures and really experience the world. I don't want my parents to lose everything because of my cancer. I will secretly arrange my own affairs, even if it is painful, I will walk away with a smile. I will visit all my relatives and friends. I won't borrow a penny, because I can't afford it. If I can, I will donate my body after I die.
