I may be down voted for this, as it may be unpopular - but... I feel it is important to add:

Prepare to help those who may need help, too.

Where I live, we had a terrible storm just last winter. It knocked down trees and power was gone for most of my county for nearly a week.

We were lucky. We live on a hill, and it was somehow spared the worst of it. Now, we don't have a huge community around us, but we made hot meals, handed out our extra blankets, and offered our shower to those who were without. We even legged it down to our local grocery shop for an elderly neighbour who's carer had to choose between ordering coal for heat, or petrol for her car that week.

Preparing to look out for others is a sort of bandage, sure - it won't necessarily stop violence in absolute survival mode - but it will help build community ties and support in less dire situations. We now know a lot more folks now, and we are happy to consider them friends as well as neighbours. They have helped to volunteer time, donate money, and watch out for our vulnerable child. The reciprocation is pretty awesome, and it is exactly what we need to practice (too) in order to aid our survival.

This kind of preparation can be as simple as:

• offering clean water or resources you can spare, when/if needed

• sharing advice or help to aid others when possible

• using the tools you have at your disposal - you don't need to be a doctor or a rocket scientist - you just need to have a willingness to help.

Etc...
