If you live life on the edge--not by choice, but by accident---then you can thank Japan for this invention. Prop, a Tokyo-based company, has introduced a line of airbags designed for human beings who suffer from epileptic seizures and for those who are "very vulnerable to injury"--or simply, clumsy as hell.
The product (priced around $1,400) is worn around the back of the head and hip, but if you plan on eating the ground, the airbag does not deploy on your face, so you're out of luck. Or you could just mind your surroundings. Hit the source to see it in action. (image via Engadget)
