Oprah is my first example. The fact that she broke out of generational poverty to become millionaire and then give as much as she does to charities and other humanitarian organizations makes real hero.

My next example is tank man. When war was broken out in China, the civilians kept getting caught in the cross fire and eventually they couldn't take any more. tank man stood in front of these tanks not allowing them to pass. he did not know what it would mean for his life. All he knew is that the war had to stop.
