Why You Should Start Brazillian Jiu-Jistu
The skills are just part of it
Brazillian Jiu-Jitsu is the pinnacle of martial arts, period. There is no other art that compares. Karate, Akido, Budo..whatever.
Jesting aside and whilst all martial arts have utility, none have the utility of BJJ. I would put my money on a blue belt over another equivelant grading in any other combat art.
