Stress test
I’m not sure exactly how this works, but it is amazingly accurate.
The picture below has two identical dolphins in it. It was used in a case study on stress levels at St. Mary’s University Hospital.
Look at both dolphins jumping out of the water. The dolphins are identical.
A closely monitored, scientific study of a group of volunteers revealed that in spite of the fact that the dolphins are identical, a person under stress would find differences between the two dolphins. If there are many differences found between the two dolphins it means that the person is experiencing a great amount of stress.
Take a look at the photograph below and if you find more than one or two differences, you may want to take a vacation.
