The picture below has 2 almost identical dolphins in it.
It was used in a case study on stress level at South Baldwin Regional Medical Center-Gulf Shores, Alabama.
A closely monitored, scientific study of a group revealed that in spite of the fact that the dolphins are nearly 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.
By the way, that's the Monk on the shrimpboat in the background. See me waving?
