The Importance of Situational Awareness in Self Defense

Is BJJ really practical for street defense where there are no rules? My understanding is that it doesn't fare well against knives and multiple attackers compared to something like Kraw Maga, Muay Thai boxing. Jocko Wilick: The most important thing is situational awareness and putting yourself in good situations so bad things aren't going to happen to you. That's of the very important first step in self defense. Second guns. If you're a small person or you might be elderly or you might have some sort of a physical limitation, then how you're going to defend yourself is using guns, using a gun.
