I am not sure exactly how it works, but this is amazingly accurate.  Read all the information before looking at the picture. The picture below has 2 identical dolphins in it. It was used in a case study on stress levels at St. Mary’s Hospital, London, England.

Look  at both dolphins jumping out of the water. The  dolphins are identical. A closely monitored  scientific study revealed that, in spite of the  fact that  the dolphins are identical, a person under stress would  find differences in the two dolphins. The more  differences a person finds between the dolphins,  the more stress that person is experiencing. Look at the photograph and if you find more than one or two differences you need to go on vacation…No need to Reply, I’ll be on vacation!

Never  take life too seriously.  
Nobody gets out alive anyway!
