I'm not sure exactly how this works, but it is amazingly accurate.
Read the full description before looking at the picture.
The picture below has 2 identical dolphins. 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 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 may want to take a vacation.
No Need to Reply, I'll be on Vacation
