Stare for a few seconds at each of the following patterns.
Are the patterns moving?  Or are they perfectly still?

The patterns are used to test the level of stress a person can handle.
 The slower the pictures move, the better your ability of handling stress.
 Alleged criminals that were tested see them spinning around madly.
 However, senior citizens and kids see them standing still.
 None of these images are animated - they are perfectly still.
 How did you do with the test??
