I read and found the following link interesting. Don't know if it's been shared elsewhere on this board. It's a common discussion amongst these threads: what should or should not constitute a blackbelt? At what age is it appropriate to award a BB to a student. Here's a group attempting to deal with that issue. It looks like they are jujitsu-ka in the main, but their discussion seems pertinent to the MA world as a whole. Do you tend to agree with their age requirements?
