Absolutely mind blowing that in today’s increasingly dangerous world, threats to your personal safety are everywhere, even here in Alaska. The News today of acts of terror to mass shootings in the lower 48 and from the unseen everyday crime in Anchorage. My wife gets upset that I conceal carry. We talked about it and I mention the danger is no longer confined to dark alleys or unstable regions. Potentially life-threatening circumstances can arise anywhere, anytime, and fast. 
The real self-defense is first of all about avoiding being assaulted or even bothered, about seeing trouble well ahead and calling police. When you carry legally and properly trained, you must be extra well-mannered, courteous and practiced using your equipment. No one should know you are carrying.
Are you prepared for a disaster, your personal safety until police arrive, until then, on your own, live or die. 
I know it seems kind of paranoid with the stuff I just wrote about, but that’s the real world for all.
