Families in BJJ
There is a famous quote in jiu jitsu that says: “jiu-jitsu é a única arte marcial que tem família” (jiu-jitsu is the only martial art that has a family), though my knowledge of all martial arts isn’t strong enough for me to attest the truthfulness of this statement, my understanding of the background and the history of the sport can certainly verify that strong family ties are what helped build this sport/martial art.
