The Zombies are coming!
Recently I read an Article on Cracked.com about how Zombies could arise and destroy the world. It's a very good article, and I highly suggest you read it.
Our culture, at the moment, seems to be Un-dead Obsessed. Zombies, Vampires, etc. But we all seem pretty safe in the knowledge that these things aren't real, and that we aren't going to be killed by Zombies. But in an effort to ruin your day, here are a number of ways how Zombies can come to being real and killing us, and how it's only going to be a matter of time.
Okay, how likely is this to happen? I mean, Brain Parasites, it just doesn't happen outside Resident Evil games, does it?
Uh, actually it does. In fact, there's already a disease out there called Toxoplasmosa Gondii.
Alright, so really it only affects rats and cats (At the moment), but that's beside the point. It still turns the rat into a zombie...Sort of.
What? Well when the rat is infected the disease must get to the intestines of a cat. So the disease takes over the rats brain, and actually get's itself eaten. Seriously.
But it only affects rats and cats! We'll be fine. Or perhaps not. Now scientific studies show that half the human population is infected with Toxoplasmosa Gondii and we didn't even know. So yes, half the people who read this are just one step away from becoming mindless Killing machines (Not technically Zombies, as we'll still be alive, but nonetheless still terrifying!)
Oh yeah, by the way, we share 98% of our DNA with rats. And that's no joke. All it'll take is a slightly more evolved version of this disease and we'll all be mindless killing machines, with no goddamn regrets. And are you comforting yourself with the thought that it may take years or Centuries to actually develop, then don't worry. Thanks to war and chemical weapons it's not going to be too long until one day the disease parasite thing is being tossed around like an AK-47.
These are toxins that slow a persons mind and bodily functions to the extent where they are often considered dead. When brought back they're left in a trance-like state where they can only perform simple tasks, such as eating and moaning.
Whilst technically still alive, the people are completely unaware of their surroundings, and only their basic motor functions still function and exist. They're as close to being Zombies as you can get without starting to decompose.
The only way to take comfort from this news that there is already a disease that can turn you into a mindless weirdo is that it, as of yet, does not make you aggressive, or cannibalistic. But it's only a matter of time.
And before you say "But this doesn't happen on a regular basis", think again. In Haiti a lot of these people were set to work on the Sugar Plantations, which was discovered after Clairvius Narcisse was declared dead in 1962, but was found roaming around 18 years later in the very same trance like state.
So yes, it's already happened, and probably is happening right now. Maybe not near you, but still happening nonetheless. All it takes is an evil supervillian to make a way for these poor souls to become aggressive, and we'll be sitting ducks. Except, not ducks. And in much more danger than ducks.
The Rage Virus
In the film 28 Days later we saw a virus that turned everybody into a mindless killing machine. But that's just a film. It's not real, so sleep easy.
In real life we have Mad-Cow disease that attacked the spinal cord and brain of the Cow, which turned it into...A mindless killing machine, that weighs nearly half-a-tonne. But that's just with cows. Oh wait, it affects human's too. In human's it's called Cruetzfeldt-Jakob disease, and the symptoms basically describe Zombies. Changes in Walking, Lack of Coordination, Dementia & Delirium.
Notice that those symptoms didn't include aggressive? But if a more advanced version of the disease could damage, let's say the serotonin receptors, and stop our brain receiving this chemical, then...You guessed it! We'd be mindless, AND violent!
And how can we be sure of this? Well, remember how I said we shared 98% of the same DNA with rats? Well they conducted a study on rats by blocking their serotonin receptors, and guess what? They turned on eachother, like mindless killing machines. So soon, (perhaps), it'll turn into a situation where this disease gets into our food supply...And if it is transferable via blood-on-blood or saliva-on-saliva it's only a matter of time before we're all mindless killing machines.
Stem Cells can be used to regenerate dead cells. It is very useful when people are ill and need a replacement organ, or need replacement tissue. However, Neurogenesis is the process of re-growing dead brain tissue.
When you die, your brain does too. Once your brain goes, there's no coming back. At all! Ever.
But there is now apparently. So if they can put a living brain in a dead body, then there we have it. Zombies.
However there is a problem, a sort of...Serious problem. This reanimation causes the brain to slowly die off from the outside inwards, which starts with the cortex, meaning after an amount of time the one part of your brain that makes you human dies off, leaving you with primitive, basic instincts. You know like a need for brains and flesh.
But don't believe me? Well have you ever heard the story about the chicken which has it's head cut off but didn't die? It's the same principle. Don't think anyone, knowing this, will ever go ahead and create some of these crazy zombies? Remember earlier I mentioned war, and chemical weapons becoming more popular than guns, etc. Well what's to say this won't be engineered upon by our enemies. The side with a dead army of psychopaths which just can't be stopped will be the winner.
So what are Nanobots? They're the biggest threat to mankind since the Terminator. Seriously. They're microscopic, self-replicating robots that can build, destroy and attach to anything. Including organs, virus' and limbs.
But who would be that stupid, as to fuse a virus/organ with a robot? Oh, we are apparently. That's right we fused these little monsters with a virus, and when the virus died? The Nanobots carried on living! For nearly a month. So there we go. There's the un-dead part of the horror.
And according to reports, it could only be a decade before they've got Nanobots that climb into your brain, and then set up and replace neural connections.
But that's all fine? I mean it's not like they'd be evil or anything. Sure, they can rewire your brain, and carry on functioning after you die and...
Wait, it's main purpose is to survive and replicate. That means going from one host to another. And how will it do that? Perhaps making the human have a sudden taste for human flesh? Then when the 'infected' goes to bite another, it'll transfer some of the Nanobots, which will replicate and turn this person into a mindless killing machine.
And even when you do die, they'll keep functioning, walking around until eventually you rot away. But that doesn't matter because everyone else will be infected, spreading the disease until we've all been wiped out. It's only a matter of time people. Sleep tight.
