Researchers have developed a temporary electronic “tattoo” that sounds an alarm when your mind
is working too hard. This “e-tattoo” reads your brainwaves and eye movements to figure out how mentally overloaded
you are. It's kind of like a Fitbit for your thoughts. This high-tech gadget was engineered for people with stressful,
high-stakes jobs like air traffic control or medicine. It would allow people in these careers to know when to take a break
before a lapse in concentration could cause serious trouble.
