Many miles I have walked alongside my two best pals by now, hunger and thirst. My grandpa used to say, I survived the nuclear war, so you can survive anything too. After all that I have been through, surviving in this dusty and cold wasteland is the last thing I want to do. I remember the good times, when our camp was still standing. The smell of hot soup and the warmth of fire, feelings I can barely remember anymore. Dad would always find insects that we could eat in the worst of times; we would never starve as long as we had him.


Days were happy until they came, the mindless wanderers. It was a Tuesday or maybe a Wednesday. Either way, the day started out as usual, dad would go hunting for food and mom would prepare the water for when I was playing around with my brother. We had both irregular skulls according to others, and our horn-like teeth did not disprove that theory. We were told it was only natural; the past nuclear war had left scars on everyone, for instance I was told that my weird skull and my animal like arm was all because of the radiation resulting in mutation. The ultimate scar however, had to be the eternal winter. By now, the cool temperatures and dry air were only natural to us.


It was around lunchtime we saw the silhouettes in the background. We thought it was dad returning with dinner, how wrong we were. I remember seeing two men running towards us, swinging from side to side. Mom screamed out ‘Cannibals’ as the men took out the knife and torch and attacked us. Then it all went blank.


When I woke up again, I could not remember anything but that from the past, it felt as if it was gone. I could not feel the usual cold, and the several smells were non-existent to me. The camp was burnt down, and my mom and brother were gone, I only saw the red carpet below me as I began walking away from my previous home.


Searching for days, I finally found my way out of the starving days: Water that led to a village. I walked and walked for ages, how long I do not remember but it felt like a marathon or at least the depiction of a marathon my grandpa gave me. The village however ignored me! I could not accept dying, I do not remember what happened next, and all I remember is that I left the village without starving again, walking side-to-side and feeling weird constantly, just like the wanderers that made my family disappear.


I remember the first time I saw my reflection in the ice, my skin was burnt, half of my face was ripped off, and my clothes were shredded, maybe the cool disappeared because of brain damage. I have also noticed my wounds healing incredibly fast, I was once told this was the first stages to something they call cancer. Walking around from town to town seemed like my destiny, the one thing I could do in life. Never finding any friends or companions. I have begun to doubt myself; maybe I have eaten every other person I have met. I heard someone scream, “There is a Kuru-infected coming our way” as I walked towards him. Every time I leave a human camp, they humans are always gone, and the red carpet is rolled out below me.


I have also noticed pain all over my body, alongside huge weird bumps on my skin, they are brown and they keep appearing. My mobility is getting worse day by day and I am getting weaker. It must be because I went into that destroyed city.


Maybe this is because of the nuclear winter too? Maybe it has decided that I can stop wandering around. If that is so, that is probably for the better…

A few generations after the nuclear war hit, we find ourselves in a small village, with a father, mother and two brothers, they have adapted to the nuclear winter, the colld and dry air, and is managing to survive. 
This family has been taught everything about the world before the war by the grandad of the family.
One day the family is attacked by cannibals, one of the brothers survive as the only one, left with his mutated body, his face half torn off, and the other side being burnt. 
Because of severe brain damages, he can not feel the cold, and wanders around with very limited thoughts. 
Hunger forces him into cannibalism, which does result in him getting the Kuru disease: Wiki link here: https://en.wikipedia.org/wiki/Kuru_(disease)
As he wanders around to find villages and food, he begins thinking about how he survives, as he does not remember eating anything. 
It does not take long before either the Kuru disease will make him too unstable to live, or the cancer he will slowly get infected with takes over, as he walks around in nuclear wastelands.
At the end, he can not stand anymore, cancer has developed too far, and he dies. 

He has mutated thanks to the radiation over several generations. A nuclear winter is a result from a nuclear war, and will therefor be at effect for a long time. 
The fact that he does not feel cold due to brain injuries, does in fact weaken him over time, as his body still takes damage from the cold.
Because of the lack of food, cannibalism is likely to be something humans will go for. The nuclear winter has killed of most food.
Getting cancer is likely, due to the massive amount of radiation affecting the cells in your body.
