When things go down, BREATHE. "Attach your oxygen first" (metaphor) so that you can help others with theirs. Stay calm. Stay alert. Be prepared with lights/candles, heat source, etc. Turn on those devices (broadband, CB, etc.) to listen for more news. In fact, prepping now will help with any nerves later.

Take care of yourself and others (if they aren't hostile).
Don't "react;" think logically.

None of us know how things will go down. But we have each other, and that's all that matters. We got this, patriots. 👍🇺🇲💙🙏
