Men who are unemployed for more than two years show signs of faster ageing in their DNA, a new study has found.Researchers at Imperial College London and the University of Oulu, Finland studied DNA samples from 5,620 men and women born in Finland in 1966.They measured structures called telomeres, which lie at the ends of chromosomes and protect the genetic code from being degraded. Telomeres become shorter over a person's lifetime, and their length is considered a marker for biological ageing.
