Well see, the problem isn't putting it on. Its having it handy when the stuff goes down.
You've got to become aware of a problem.
Then you've got to arrive at the decision the problem needs such a response.
If you've got it right next to you, then you've got to put it on. If not, you've got to go get it.
That's a lot of time. It could be too long.
Storing body armor so its handy may, or may not, be an issue for you. Mine's on a shelf in my closet. Often things get placed on top of it. Its not a good idea to hang it on a hanger; the proper way to store it is to lay it flat. If you've got a place to do that, then do it. But you might not be next to it when you need it. In fact, that's probably more of a likelihood than the scenario that you'll have it next to you. Then what?
When I was in Cuba, we went on week long "react force" assignments. Even with that assignment, we stowed our gear someplace to go get it when we needed it. When we had a defector cross the fence or swim onto base, we were often doing some kind of work when the call came in. Most often, it was at night and we were sleeping. It takes time to gear up. There are some measures that we can take, but in the end they are uncomfortable and inconvenient to implement during our daily activities.
Like I mentioned. I have it, and if time provides me that option I can get it. But its not in my plan. In the end, its your life, and only you can make the decision appropriate to your lifestyle. If you want to do it, it really doesn't matter what we do. Nor should what we do make much difference in your decision.
