In every moment people die from different reasons and the most common is the accident. You walk on the street and a pot with flowers falls into your head and everything ends, you are innocent. Either you don’t understand what was in your mind when you ran in front of a car without looking both sides. This time you are not so innocent even if you invoke that you were temporary insane. I think machines of all types are involved in accidents. We invented these toys that kill us by mistake.
You can imagine that every man has a number, when a human being is born this number is increased and when he dies it is decreased. Everything happens so fast because in every moment human beings are born or die.
Considering that in every thing is a balance and then on Terra should be the same: to be a constant number of people because otherwise the planet would lose its balance and it would break apart under its weight.
When the number increases over the admitted limit it is used a system which picks a random number and the man with that number dies in an accident of any type. Even killers invoke the same reason: “It was an accident” but nobody believes them.
If the number decreases too much then babies are born by mistake. If they live or die depends of the same “lottery” system and of the number they get and it changes at every second.
The reality is relative and this could be one of its faces
