I was thinking of starting Krav Maga, do you know anything about it?
Of course ive been practicing it for a long time, I use Krav Maga for its focus on real-world situations and its extremely good efficiency. 
Interesting, where did Krav Maga originate?
Well it first derived from the street-fighting of Hungarian-Israeli martial artist Imi Lichtenfeld, who made use of his training as a boxer and wrestler as a means of defending the Jewish quarter against fascist groups in Bratislava, Czechoslovakia, in the mid-to-late 1930s.
