A new blood test that claims to predict your biological age and how much longer you will last has been developed.  A research company based in Spain, developed the test and is working on approvals throughout Europe and America. Now available in the U.K , the test measures the length of telomeres, a DNA structure which controls the longevity of dividing cells. The shorter the telomere, the faster you are aging. A very specific blood test can determine telomere length and, based on the length can use an algorithm to assess longevity based on current lifestyle. The test will give people an idea of the speed at which they are ageing, and a general assessment about their state of health. The cost of the test: In England the price is set at £435, which is roughly $705 at today’s exchange rate.

One benefits of a test like this is that you have the opportunity to make lifestyle changes that will benefit you and increase your lifespan.

Some critics claim that the test measures the length of telomeres on DNA in white blood cells in the plasma. White blood cells are involved in immune defense, and increased production during sickness may skew the reading of the test.  The test also fails to look at other measures that can indicate the overall health of a person.
