It takes a long time for men to reach milestones. And the milestones achieved will be a stepping stone for other achievements. Men find it dear to let go of milestones through death.
Sometimes, men want something that is absolutely impossible, eternal life. Various researches and experiments, treasures and knowledge were sacrificed to gain immortality. Obviously and absolutely impossible.
Everyone who desires immortality his mind is only filled with lust. They think all his achievements are the efforts of men. Instead of destiny written by the universe.
