I am not sure exactly how it works, but this is amazingly accurate. Read
the full description 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.
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.
