Hi, and welcome. I prep for multiple reasons, not 'the end of the world' or anything that dramatic. I like knowing that I have a pantry full of food if something happens to our supply chain. I've seen grocery stores stripped bare in twenty four hours ahead of a storm. I also get to eat much healthier food, that I grew and preserved and know what chemicals and preservatives went, or didn't, into it. I also can find drinking water, and safely purify it if the tap dosent work one day. I have multiple ways to filter water now. As far as security, just watch the news and see if you don't agree that the police aren't capable of stopping crime. I like knowing that I can protect myself well if someone tries to hurt us or take the supplies I've built up. All these things are common sense to me. Food, water and security are the three big things that any father or parent should want for their kids and family. If anyone thinks this is weird or crazy then I don't think enough of them to care about their opinion. Good luck in your learning here and elsewhere.
