I can't say I remember what it was like to find out the truth about Santa Claus, but I doubt I took it as hard as when I found out that superheroes weren't real.
Even though this realistically meant there was only a slight chance of Spider-Man helping me if I was in trouble if he actually existed, that chance went straight down to zero once I hit that age.
But although there aren't really superheroes with actual powers patrolling the streets, there are a few extraordinary people who are taking up their mantle to do some good in the world.
And one Florida man is seriously dedicated to the way he does it.
