For around the price of a laptop ($1,400), you can protect your grandmother from falling down. Prop, a Japanese based company, has created the perfect present for those elderly relatives: an inflatable airbag, which they displayed at the International Home Care and Rehabilitation Exhibition in Tokyo. It’s only 2.4 pounds, but it looks like a fanny pack and is currently available in Japan.
The airbag works like this: When a person wearing the bag is about to fall backwards, electronic sensors signal the airbag system to pump 3.9 gallons of gas into each of the two bags, just in time to carefully protect the person from falling on their head and rear end.
