Your second gun should be a good hunting rifle. Bolt or semiauto is fine, and the ideal caliber is .308. Ammo is cheap and widely available because you can use 7.62mm NATO as well. It also has enough punch to take down just about any game. A handgun is a lower priority, but handy to have. Go for a high-capacity 9mm semi, if you’re buying one. Again the ammo is NATO standard and easy to find.
Up until that time there had been no weight categories. As a result of his stunning victory, weight categories were instituted world wide in judo. Unless you are a highly advanced black belt, advanced in inter-club competitions to the seventh or eight degree the first guy who comes along who outweighs you by probably 50 or more pounds is going to stomp you. Anyone who has had experience in street brawls is going to stomp you. There is a reason why people say, “God didn’t create all men equal, Samuel Colt did.”
I confess that  I can go for days eating the same meal of baked potatoes over and over again.  That said, most people need and want variety.  This is especially true for children, the elderly and the infirm who may already be picky eaters.  Plus, you need a variety of foods items in order to get a full complement of nutritional value from your meals.

They’re also vegan and nut- and lactose-free, with very clear nutritional info.
It’s mostly natural disasters we’re preparing for. I’m concerned about a war’s potential knock-on effects on the food chain, although I haven’t dug a bunker in my garden or anything. And then there’s Brexit. If that doesn’t go the right way, who’s to say we’ll be able to get hold of the things we can get hold of now? But, realistically, we are mostly likely to be affected by flooding or severe snow. There have been times when we have been cut off, unable to get out. We’d need to be prepared if that happens again.
It isn't hysteria, and GMO isn't 'evolution'. One of the biggest issues for preppers and survival is that GMO seeds will not reproduce in the same way if the seeds are saved and re-used. In fact, in many instances (maybe all?), it's illegal to save the seeds and re-use them! It's far better to track down heirloom seeds that are native to your area and/or compatible with your climate.
