Man knows not his time... but, a new test promises to give an accurate estimate of the number of years you have left. All it takes is some saliva.
One company is offering what they say is a biological age test that reveals how much time you have left to live. It's all part of DNA strands and these things called telomeres and they can get an accurate count just from some spit.
The test will set you back $499. Even though the test does nothing to stop or reverse the aging process, it seems to have a big effect on some of the customers. The son of one customer said in The Guardian, "It was such a relief for her, because it gives her a newfound hope about life planning."
