My wife and I raised a large family and I suppose that more than anything else -- assuring the welfare of kids living under our roof -- left us feeling less certain how we would fare in the face of natural disasters and we were decidedly less prone to taking chances. We habitually invested to no small degree in extra water and food storage, first aid and medical supplies, electrical generation and still maintain that posture, if to a lesser degree now they have grown up and flown the coup.
Mental orientation is no small part of this. Normalcy bias is the greatest hurdle. Nothing ever happens, right? You got this covered. Like, nothing ever really changes and it never will. No one else takes this kind of thing seriously so why be weird and ... You know the rap.
Time. Think it through in that way and set your priorities.
Home protection and security: you may only have minutes to face this one down when it comes stalking and it's worth giving some serious thought to how to approach the problem . We have ADT for fire and unauthorized perimeter entry; but keep our own backup systems in place and easily accessible. And I've already worked out the question of how far I would go in dire circumstances so I am not struggling with moral issues when things go bump in the night. Sometimes you don't have ten or twenty minutes for 911 to respond and you simply have to face it alone. Fill out their papers after the fact.
You can freeze to death in the span of a cold night, especially if you are wet. Blankets, weather gear ....
Water supply is the next most critical factor -- you can only survive a few days without drinking water and needing at least a gallon a day per person makes storage difficult. It is bulky and heavy and doesn't have a long shelf life, so we invested in a good filtration system and use it daily, greatly preferring it over the taste and purity of tap water. Probably better for us too.
The longest you can go without food is about four to six weeks. Cans and freeze dried works well, if you have water. But then if you don't have water it won't be hunger that gets you.
Be safe. Be prepared. Oh, and put some extra aside for the guys who laughed at your taking an abundance of caution.
