Designer Michael Mathis and Gerda Hopfgartner has come out with an interesting idea for a watch called "The StressWatch" which can be used to show you your stress levels. As you can see from the picture above, the blues and greens that you see there means that you are mellow, but pink, red or orange means you are stressed. Actually the idea of this interesting watch is not to be a stress exhibitionist, but to remind you to slow down your breathing and use visual biofeedback to calm yourself down. This device is just a concept right now, but it should be made reality.
