Why do i see 10 year olds or 14 or 16 year olds with black belts, second degree blackbelts,, or even higher. I have a feeling these american karate instructors are using belts in order to attract customers, but karate is a life process, they can’t possibly master the true essence of karate in just 4 years or something..and certainly at 16 a master…without having had maturity? I will consider a master at 40 or 50, after years of training and developing spiritually not at 10 years old.
