Blood test that could reveal lifespan going on sale

LOS ANGELES

Scientists say the test can show how fast someone is aging and estimate how much time they have left to live. The test measures structures on your chromosomes, which are believed to be an accurate indicator of the speed at which you are aging.

Medical researchers say the test has a lot of potential for catching disease, but could also easily be abused for unethical reasons.

The blood test will go on sale in Britain later this year.
