Why do you have to be 16 for TAGB 2nd dan?

Answer 1

Asia culture places a great deal of value on age. In most schools a child needs to be of a certain age to attain the more advanced rankings, especially at the black belt levels. You have to show experience, training, wisdom, and other factors that cannot be attained at an earlier age. Young people who put in the time and training sufficient to earn a dan rank are often presented with an equivalent poom rank which can be converted to a dan rank following their sixteenth birthday.
