Refuse to be a Victim. Like the boy scouts say, be prepared. Check your situational awareness status and act accordingly. Always have your gun where you can have easy access to it.
At age 66, I'm still a pretty fit guy. One would never know by looking at me that I have a pretty severe spinal cord injury. My neck and back have more metal in it than most VW's. I cannot afford a right hook to the head. My situational awareness is aways condition red. It's not fun sometimes but such is life. My gun is always on my hip and in condition one. Don't mess with this old guy.
May the Schwartz Be With You.
