A blood test that should be available in Europe by the end of this year, could indicate how fast you're aging and how much longer you will live. Would you want to know?

The test measures telomeres,structures on the end of each of your chromosomes, which scientists think may hold the key to determining a person's "true age."

Research has linked shorter than average telomeres to shorter than average lifespans. However, at this point, there is little evidence suggesting that if you have longer than average telomeres  that you'll live any longer.

The Huffington Post says the test will cost about 700 dollars.
