I'm not sure exactly how it works, but this is amazingly accurate.
Read the full description before looking at the picture below.
The attached photo has 2 identical dolphins in it. It was used in a case study on stress level at University of Waterloo Hospital. Look at both dolphins jumping out of the water. The dolphins are identical.
A closely monitored, scientific study of a group revealed that in spite of the fact that the dolphins are identical, a person under stress would find differences in the two dolphins. If there are many differences found
between both dolphins, it means that the person is experiencing a great amount of stress.
Look at the photograph and if you find more than one or two differences,you may want to take a vacation
