Creepy. As. Hell.

I was wandering around on the Internet today...and found this disease called "Fatal Familial Insomnia." And pardon my English, but this disease is just one of the most fucked up diseases of all time.
All right. I only found this today, so my understanding of this is not perfect. Feel free to research and correct me.
So what happens is that there are proteins, like, everywhere in your body, yeah? So there are proteins in your brain. These are prions. Well, what happens sometimes is that the proteins in your brain mutate. (The mutation is normally genetic, and 50%. If your mom had it but your dad didn't, you've got a fifty percent chance of getting this.)
Once this mutation happens, you are, essentially, dead man walking. The prions, essentially,eat the part of the brain that lets you sleep. Okay? So you have constant insomnia, until you die, which is in about nine months after total insomnia hits.
The bitch about this disease? You can't sleep through it. The lack of sleep gives you all sorts of issues. You lose control of autonomic systems - like sweating. Stuff you'd do normally.
But you are still awake. You know what's happening to you. You know you're going to die. You can talk to your family, despite the fact that you have not slept for nine months.
In my opinion, that's the most horrible fucking thing in the world. Fatality is 100% because once you've lost the ability to sleep, the little lizard in the back of your brain...you know, the one that says "breathe, sweat, eat, blink"...goes insane.
And you're awake to see it happen.
