" Going for a run on your own could be bad for your health, research has suggested.  Professor Elizabeth Gould, lead researcher of the Harvard University study, said going solo could raise stress levels and interfere with the production of fresh brain cells.  In experiments the researchers studied two groups of rats as they ran on exercise wheels.  The first group of rats exercised by themselves and the second group exercised with other rodents.  After 12 days the researchers did tests to estimate the number of new brain cells in each rat.  They found that the rats who exercised with others had more than twice as many new brain cells as the rats who exercised alone.  Tests also showed that the rats who ran alone had generated fewer new brain cells than rats who did no exercise.  Professor Gould told the Daily Mail: &amp;quot;Our results are evidence that social interactions can buffer the body and brain from stressful experiences.&amp;quot;  Previous studies have shown that while exercise can help boost brain power, too much can slow down the production of new brain cells.  Professor Gould and her team reported their findings in the journal Nature.  \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
