But as you get older, your courage attracts gunk and crusty things and dirt and fear and knowing how bad things can get and what pain feels like. By the time you're half-grown, your courage barely moves at all, it's so grunged up with living. So every once in a while, you have to scrub it up and get the works going or else you'll never be brave again. Unfortunately, there are not so many facilities in the world that proveide the kind of services we do. So most people go around with grimy machinery, when all it would take is a bit of spit and polish to make them paladins once more, bold knights and true.
