I have realized from a knife attack I survived, when in my younger years, "speed is your friend, against surprise" and since adrenaline kicks in during a surprise, you have the momentary advantage of speed to run, faster than you normally would. I was able to dodge and run for way a longer time when that attack happened, I was not injured in that incident, but it taught me, that speed saves, surprise kills. I especially see it in the national geographic movies when wolves attack their prey, or cheetahs stalk and hunt down their prey, they use the element of surprise and speed along with violence of action to take down their prey. Now speed does save the prey from time time as the antelope can dodge and run away at times from the predator, in my case, I was able to dodge and run away, very very fast. I also like to point out that adrenaline can numb you in case of damage done to you, if your cornered, which can work to your advantage as you could then run/move away very fast from the attacker.
I also learned from someone else that:
1. Barriers
2. Time
3. Distance
Are you friends to mitigate violence on you.
Of course, SA or Situational Awareness is your number 1 best friend, above all else, to avoid conflict/violence, as other ladies have mentioned before.
