The results of the tests might also be of interest to companies offering life-insurance policies or medical cover that depend on a person’s lifetime risk of falling seriously ill or dying prematurely. However, there is a growing body of scientific opinion that says testing the length of a person’s telomeres could provide vital insights into the risk of dying prematurely from a range of age-related disorders, from cardiovascular disease to Alzheimer’s and cancer. “We know that people who are born with shorter telomeres than normal also have a shorter lifespan. We know that shorter telomeres can cause a shorter lifespan,” said Maria Blasco of the Spanish National Cancer Research Centre in Madrid, who is the inventor of the new commercial telomere test. “But we don’t know whether longer telomeres are going to give you a longer lifespan. That’s not really known in humans,” she added…
Asked why the general public would be interested in taking a telomere test, Dr Shay said: “I think people are just basically curious about their own mortality. If you ask people what they worry about, most people would say they are worried about dying.”
He added: “People might say ‘If I know I’m going to die in 10 years I’ll spend all my money now’, or ‘If I’m going to live for 40 more years I’ll be more conservative in my lifestyle’. The worrying thing is that if this information ever got to a point where it is believable, insurance companies would start requiring it in terms of insuring people.
