Re: Why Test?
There was a guy in a dojo I heard of, who just kept ducking out of testing. Everytime he was to be tested or when there was testing, he didn't show up. This went on for twenty years.
Things got to be a little strange when he started teaching. Of course he had twenty years of Aikido and he knew his stuff. But a visitor would just see a white belt instructing the class.
Finally the head instructor saw him one day and had an impromptu test. He passed and was given a black belt.
