If we didn't know better (and we don't), we might think that narcolepsy was becoming an epidemic. We just mentioned the "Alert Master"--a device that sounds an alarm if your head drops while you're behind the wheel--and now we learn of "MyDo Bururu" from Japan's Vision Optic, a pair of glasses that pretty much does the same thing in or out of the car.
They have an earpiece that vibrates whenever its wearer's head drops below normal conscious angles, an alarm that can be set to four degrees of intensity, according to Plastic Bamboo. (We wouldn't want to experience Level 4, whatever it is.) The natural companion? The "MugMouse," obviously.
