Researchers have developed the £435 test, which they say accurately measures the length of a person’s telomeres, which is thought to be linked to longevity. Telomeres are sections of DNA that cap the ends of chromosomes, protecting them from damage and the loss of cell functions associated with ageing. Shorter telomeres are thought to be an indicator of faster ageing. A Spanish firm, Life Length, has developed the new commercial “death test”, which it says will show people how long they have to live.
