Mostly general preparation for things that might happen. Whether that's a simple thing like taking a basic first aid kit when I go hiking to making sure I've got a well-stocked pantry as winter approaches, it's just about considering the "what if" questions.
As with most things there are some who don't even consider what happens if they can't get what they need when they need it, some who are so well prepared they could hunker down in their home and not come out for months or years, and others who sit somewhere between the two.
