Six times a day part 84

In just a few short weeks, tens of thousands of newly minted doctors will start the most intense year of their training: the first year of residency, also called the intern year. A new study suggests that between now and next summer, that experience will make their DNA age six times faster than normal. And the effect will be largest among those whose training programs demand the longest hours. The findings about the effect of residency focus on the stretch of DNA called telomeres -- which keep the ends of chromosomes intact like the plastic end of shoelaces. The discovery that telomeres shrink in an accelerated way among interns suggest the importance of ongoing efforts to reduce the strain of medical training. But the researchers say their study also holds implications for other professions and situations that expose people to prolonged stress and months of long hours.
