What does a black belt mean these days? That you have memorized some patterns and kata? Done 1vs1 at slow motion speed? Ya pretty much I know a bunch of kids who are black belts. I myself am a judo black belt and am 16 but in judo you have to work for it, grapple rohndori ( a form a full force sparring with no striking ) so in judo if you get a black belt you have earned it not memorized it and i'm sure some others are arts and schools are like this but not many that i've seen, a black belt gives them a false sence of security but they can't really fight. But face a black belt use to mean that if you caught him on a bad day in a back alley you were in trouble...
