If you are feeling under stress, you might want to take a look at the picture in this post. At first sight, it appears to be a picture of two identical dolphins jumping in the sea. But there is more to it than meets the eye. Scientists have discovered that people who are under stress tend to spot a number of differences between the dolphins: in fact the more differences noted, the greater degree of stress.
So take a look. If you don’t see two identical dolphins, you may be in need of a break!
