What is needed for someone to become hero?
We've plenty situation in daily life where we can do something good and positive.
Did you ever gave money to some poor guy on a street- this would be HERO FOR THE DAY?
Every penny I had on me at the time, I walked a long way home.
I don't think it was heroic, I have been there myself (homeless) and not quite far away from it again.
Its just something you do, to help some one in distress instinctively.
But it has become less these days, due to personal reasons.
