Yale researchers are working on a blood test that will measure how long you have left to live. It's a 23AndMe-style test and what it does is measures your blood and checks for health, the age of your cells.
Question is, would you want to know when you die? The test obviously won't tell you how you will die unless an abnormality shows up during the testing. And of course it won't tell you if will get hit by a car or any other accidental thing. But sometimes knowing could be good so you can make sure to live your life to the fullest.
