Look Out, You Old Bag

Prop, a Japanese company, has invented a wearable airbag to protect elderly and disabled people from falls.

The device, controlled by sensors, is capable of inflating in just one-tenth of a second when trouble is detected.

the bag is designed to cushion the back of the head as well as the buttocks, which is great unless you happen to fall on your face, at which point I suppose you're on your own.
