Interesting.
Years ago I wondered how people would respond if they somehow could be accurately told the date and time of their eventual deaths?
Would they resignedly accept their fates, become despondent and take their own lives, or go insane?
The variety made me rethink if our governments are withholding real UFO information out of real fear of the responses people would make?
If you knew you would live to a ripe old age of 80-90 you would be relieved and take life easy as it goes.
If, on the other hand, you knew you would only live to be 20-30 or even 40, you would become hell-on-wheels uncontrollable and be a danger to yourself and others..................
That is sort of the story behind Isaac Asimov’s ‘Spacers’ in his novels and Foundation series.
The Spacers are Earth people who went out and colonized planets in 50 solar systems beyond ours.
Hundreds of years passed and their descendants eventually come back to Earth and they are not welcomed.
The Spacers live in bubble domed cities that filter out every germ and dust particle from the Earth’s atmosphere. They are extreme germaphobes. They do not mix with Earth people and vice-versa.
They live to be 300 years old and are disdainful of Earth people who only live to be 70-90 years.
They have spaceships and superior weapon technology but they are so protective of their own lives that they cannot fight an actual war and will withdraw from a battle, whereas Earthers will fight to the death to repel them.
They eventually die off because of infertility except for one planet, Solaria, that becomes a strange place that only has a very small population of asexual (clone) reproducing people and thousands of robots to take care of them. They will also kill anyone not from there who lands on their planet.
Robert Heinlein’s first published story, Lifeline, deals with that very topic.
