Simple test that will prove your level of stress - What do you see when you look at this picture?

A digital image has emerged on social media showing an optical illusion that apparently determines how stressed we are. 

The simple stress test was initially said to be the work of Japanese neurologist Yamamoto Hashima. Your stress level comes down to what you see within seconds. 

If the image is still, you are calm; if it moves slightly, you are stressed and if it moves like a carousel, you are very stressed.
