Long Term Unemployment and "Premature Aging"

There was a research paper published in 2013 stating that younger men who had dealt with long term unemployment were more likely to suffer from premature aging. It described premature aging as people having shorter telomeres (I don’t know what that means other than a basic search).

This seems like it would be a serious problem given the late 2000’s recession in the USA and even worse conditions in much of Europe. Have you read any analysis on this paper and, if so, do you have anything insightful to share, such as whether you agree with its conclusions, or how you would go about minimizing the predicted affect on a patient who was formerly LTU?

A citation would be a good place to start.
