People who leave education with fewer academic qualifications may grow old faster, according to a DNA study that
compared groups of people who spent different lengths of time in education and found the ones who spent the least time had
shorter telomeres or "caps" on the ends of their DNA, a sign of premature aging in cells.
Co-funded by the British Heart Foundation (BHF) and the Medical Research Council (MRC), and led by University College
London (UCL), the study used 450 volunteers from the ongoing "Whitehall II" study, which started in 1985 to investigate links
between social class and health.
