Rumours of my death have been greatly exaggerated (by a website)

A simple blood test may soon be able to tell you how long you will live. Just roll up your sleeve, ready for a nurse to take a syringe-full of blood for testing. The blood will be examined for biomarkers. Fourteen of them. Then, a laboratory will tell you, with 83% accuracy, when you will die.
Now, we’ll come back to the accuracy in a moment, but why would anybody want to know when they’re going to die?
