If you drew a clock around you, the “12” would be straight ahead, the “3” directly to your right, the “9” directly to your left and the “6” directly behind you. Always check your “6”. That means look behind you. We had a case recently near by where a couple were killed while walking on a park path. No idea why–looked like a thrill kill. What’s significant is that they were hit from behind, knocked down and beaten to death. Now, I don’t know that seeing the attack coming would have done them a bit of good. But it might have. Additionally, if you are alert, attackers may choose to find some other victim.
So always check your “6” and stay alert.
