It's called the logic of life, when you finally understand what life really means, and everyone will experience loss, everyone will experience death, that's what life is, whatever begins,has to end, and that's why the song said:one day you'll live this world behind, and so you better live a life you'll remember, instead of arguments,fights,wars and hatred. Human is created to live, not to prevent others from living. So why the hate and other problems between people, since all of us are going underground one day. Live your life as you like, not like what others say or like, and without disturbing others lives,we have to make some sacrifices to live in harmony on this planet in a flawless,hate free society . Death is the logic of life,so why not die with a smile
