Would you like to know when you’ll die? It’s a scary question for many, but one which could be answered using
a new blood test. Spanish scientists have invented such a test that they say will estimate how much longer you will
live. The seven-hundred-dollar test measures the length of telomeres in our DNA. The longer they are, the longer our
lifespan is. Telomeres control how often our cells divide to make new ones and are thus connected with aging. The
company behind the project, Life Length, says the test will give people an idea of the speed at which they are aging
and a prediction of when the end might come. Critics have been quick to attack the test. They say it could lead to
insurance firms demanding that people take the test before issuing policies. Researchers say the test could lead to
breakthroughs in heart disease. Professor Maria Blasco, inventor of the test, believes it is important, saying: "It will be
useful for you to know your biological age. Maybe you would change your lifestyle habits if you find you have short
telomeres."
