Very interesting article. I did not know such details about jiu-jitsu. Just a month ago, my friend told me about it, and it looked really cool. I found the books on jiu jitsu as I got interested in this type of fighting. I learned more about Jiu-jitsu techniquesand understood, it can help me in health and in life as well. I have already signed up for courses and hope to become a professional fighter.
