Hypervigilance is a hard way to live life. The stress associated with doing so causes all manner of stress-related disorders, and causes people to lose the ability to enjoy life; the ability to, "stop and smell the roses."

Be polite, be professional, and have a plan to kill anyone around you. Train yourself to be able to react to a situation. The best among us do not have the magic ability to preempt an attack, even when it is known to be inevitable.

I know they say that an ounce of prevention is worth a pound of cure, but in day to day life, that is not a practical approach.

The person that lives in condition zero has a 0.0001 percent chance of being the victim of an attacker. The person that lives in condition orange has a dramatically higher percent chance of being the victim of a stress related disorder. Be somewhere between, be aware, but don't pitch a fit when one of your party wants to unwittingly take the tacti-cool seat.

The person that invests so much in protecting them and theirs that they burn out, and die of stress, or they miss out on the good experiences they could have shared with their family... sad.

Speak softly, carry a big stick, be ready, and accept that a coordinated surprise attack will catch you by surprise. Be ready to respond, but don't let life pass you by as a result of hypervigilance.
