who is a hero

Yesterday I wasn't able to post anything, partly due to poor planning and in the search for my own definition of a hero. I found that according to me; a hero is one who seeks to postively affect/change the status quo for the majority in the long-run. Though one might be tempted to condemn my definition for being ovely simplistic; it is what I came up with and what am proud of. Over the next few weeks I will seek to see what others have defined the word as and look into to modern day hereos.
