The police, firemen and soldiers are not the only true hero's left. There are other legendary individuals like athletes, sportsmen, inventors and artists that are described as heroes in the community for their positive influence.
The teacher that inspires a student to achieve more than he ever thought possible before. The parent who supports their child to become something that the parent would not have necessarily wanted to the child to be. The friend who is there to help you go on when you think you have lost everything. They are all heroes.
Firemen, police and soldiers are doing jobs they chose and are paid fairly for the service. That doesn't really meet the hero definition for me. Granted, some do go way beyond what is required and could be considered a hero, but not for doing their job.
There are everyday people that perform heroic acts every day. The people that volunteer at the homeless shelters the animal pounds and other places. The person walking their dog that stops to pick up a piece of trash. There are actual people that dress up in costumes and have superhero identities that spend their days helping the less fortunate. There is a documentary called superhero all about it
