Burnout might seem to be a modern condition - the result of our ever more hectic lives.
But a new book suggests such stress was just as commonplace in the Victorian era, only then under the guise of neurasthenia.
The nervous condition - a feature in 19th century literature - was seen as a failure to cope with the pace of industrialised life.
David Schuster, a professor of history at Indiana University-Purdue University Fort Wayne, says the symptoms of burnout and neurasthenia are very similar.
In both cases, patients experience depression, lack of ambition, insomnia and headaches.
