A hero is someone who does good in all possible ways for everyone. His actions implies humanity and wisdom. Bollywood actors are called hero because they play a virtual or imaginary role in a movie , that is they are able to be good on that part, so they are called hero. Because they act virtually. While our Indian army are the real heroes because they act in reality for their country. What they do is just not visible to us , but is always admirable and appreciable. They fight at border so that we can be happy at our homes. They will always be the real heroes of India.
