I'm not sure exactly how it works, but this is amazingly accurate.
The attached photo has 2 virtually identical dolphins in it.
It was used in a case study on stress levels at St. Mary's 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 observe differences between the two dolphins.
If there are many differences found between both dolphins, it means that the person is
experiencing a greater amount of stress.
Look at the photograph, and if you find more than one or two differences, you may want to take a vacation. (Keep scrolling down)
