I'm looking into learning some self defense and I was considering Krav Maga.
Wow, Krav Maga is a military self-defense and fighting system, that's impressive!
So does that mean you recommend me learn it for self defense?
Well, Krav Maga does have a philosophy of defensive and offensive maneuvers, so it would be great to know. 
Awesome thanks. Do you know how long these techniques have been around or who uses them?
It was developed for the Israeli Defense Forces.  Don't mess with them.
Oh wow so it was developed by people from the middle east. I guess I never really thought about how they fought hand to hand combat. 
Imi Lichtenfeld used it and developed it.
