We just live in it.
Shades of Doctor Pinero. Robert Heinlein’s first published short story was called Lifeline. In the story Dr. Pinero developed a machine that could precisely determine the time, but not cause, of a person’s death. In the end evil agents of the insurance companies killed Dr. Pinero and destroyed the machine and all documents. The last one they destroyed was a piece of paper upon which Pinero had written the date of his own death.
Now more than 70 years after
first appeared scientists in Finland have developed a test that purportedly will do the same.
The truth is that the test isn’t being developed to predict death, but to find hidden medical conditions before they kill patients. Which overall is a good thing, but the story on AOL it more exciting than the truth.
Still, Heinlein’s predictions of the future continue to be more accurate than many of those of so called scientists.
