Children see things, untainted, pure, and open-minded.
A reality limited only by imagination and experience. This leaves the door wide open for them to believe that, there could be a Superman, a Bionic Man, a Santa Claus, a Fonzie, or even a Barney. But nowadays, when I think of heroes, I think of someone who is, at least real. Someone like, the guy on the evening news that helped avoid a tragedy, by jumping in a flooded river to save a boy's life. These lifesavers are heroes, but are quite often, quickly forgotten.
