And if it's all true?
Say there is a massive war that starts, WW3... or a more natural thing, like severe storms covering the entire planet... or when the galactic alignment happens, there's a massive energy wave that hits... the axis flips... what then? Preparing for the worst case scenario is never a bad thing, of course you're always hoping for the best outcome possible, but being caught with your pants around your ankles is never a good thing.
You never know when your time is going to come, whether it be due to a natural death, an accident, disease, or something happening because it is time for the entire world... being prepared to ensure your own survival, as well as that of those around you, helping anyone that comes to you needing it is not going to kill you. Make the most of the time you're given and laugh until you cry, love until it's painful, cry until you can't see and wallow in the pain just so you know you're still alive... humans are survivors, we adapt, we change with the flow or at least we're meant to but in these times, there are far too many people who wouldn't last 24 hours on their own with no structure, no law, no oversight by the government. IF something happens, which side are you gonna be on? The one that's got their pants around their ankles or the one that prepared for any possible outcome and was ready, even though everyone around them said "you're crazy"?
Screw school systems, learning how to build an atomic bomb or some shit... start learning how to live off the land, be prepared to free climb a 1000 ft cliff for no other reason than it may be you're only way out... plan ahead, have more than one way in and more than one way out of wherever you are and wherever you're going. Have non-perishable food stored, clean water to drink, medical kits that allow you to do even minor surgery if you have to. Stop poking fun at the doom and gloom because if history has taught us anything, if it's happened before it will happen again. Be that a world war, a Holocaust/genocide, an axis flip, an ice age...nothing is for certain and the only thing you have is now.
Rambled a bit there and got a bit off topic, but come on people. It's nice to sit around and joke, but who here actually does not have the "what if" in the back of their heads? Think about it.
