You don't have to be Asian to enjoy martial arts, you just have to enjoy sweaty rubber on your naked feet and middle aged taskmasters barking orders at you. Martial arts teach you discipline, respect and most importantly self-defense, because a good karate chop will make the bullies forget about your dyslexia, scoliosis and constant cowlick.
Dojos are the best place for self-esteem and ringworm to bloom.
