Lifeline

The Daily Mail reports on a new blood test that will indicate how long you have to live.  Robert A. Heinlein wrote a short story about this very idea, way back in 1939.   In the story a fictional Dr. Hugo Pinero invented the technique.  The story opens with Dr. Pinero invited to a scientific convention and getting trashed by disbelieving scientists.  Pinero's invention plays hob with the life insurance business, who hire hitmen to do away with him and make the world safe for life insurance salesmen.
   Science fiction comes to life, again.
