There are REAL superheroes in this world.
I frequently visit the BioMatrix website, and I just read the newest article - http://www.the-biomatrix.net/who-are-the-real-life-superheroes.htm - and learned about real-life superheroes, who are often referred to as "Reals".
Apparently there are some concerned citizens out there who have been taking to the streets over the last several years in attempts to better their community and effect change. They wear costumes and go by names like The Dark Guardian, Geist, and Citizen Prime. They do good deeds like pick up litter, give food to homeless, and occasionally try to take care of petty criminals.
While there's something naturally off about someone willing to don a costume and walk the streets at night, I think that anybody who is actually working to make the world a better place seems pretty sane.
Check out the BioMatrix article and all of the links it provides for more info. It's pretty cool.
