Iritech Inc has developed a device that measures stress by photographing your eyes and analyzing how your pupils react to the camera flash. The machine is examining the response of the autonomic nerves (the nerves which you don't consciously control) and decides if there is evidence of stress. The machine will print out a detailed analysis, going so far as to tell you if your "skin conditions" are caused by excess stress.
No distribution information but I think it's a good idea. Although it's still measuring a biological response to stress, there are mental health implications which are so routinely ignored by patients, doctors, and insurance companies. Imagine being prescribed a vacation if your cortisol levels were found to be sky-high.
