This photo was used in a study on stress at St. Mary's Hospital. 

After you read this look at both dolphins jumping out of the water.   The dolphins should appear identical, however the closely monitored scientific study found people under stress will find differences in the two dolphins.  The more differences you see, the greater amount of stress you are probably experiencing. Look carefully at the photograph. If you find more than one or two minor differences between the two dolphins it may be time to consider a holiday.
