I came across this video after randomly googling BJJ schools in New York, and I ended up watching the whole thing. I believe a friend of mine trains under these folks. I have never actually met or worked with Master Mansur or Professor Milton Regis, but after listening to their story and everything they have been through together, I felt compelled to share it.
This is a genuinely impressive and moving story about courage, honor, and the bonds that define a martial arts family. Well worth your time.
