In a true post-civilization scenario, our life expectancy will drop by at least 50%, so we should come to terms with that.
There will be very unpleasant scenes and people will die from the slightest things, that will be so, who can not come to terms with it for the better to never experience the post-civilization scenario or to go before.
This should not be a criticism, but you have to learn to deal with it, everything has an end, but the end in a post-civilizational scenario hangs over us every day.
Our European ancestors had the motto, it was more honorable to fall young in battle than to suffer as an old person from various things, it was just fate and given, it was normal.
In a post-civilization scenario, a diseased tooth can mean death, but that is not why I remove all teeth.
There are too many risks that can lead to death, even the simplest accidents, if you break your leg you are written off.
I always say to myself, if my goddess calls me, she will get me, there is no way around it, at this moment you should hope that it is over quickly that you can go without great suffering in the next world, we are all expected.
