Japanese manufacturer Prop is now selling wearable airbags for old folks and people who just can't stand for long.
Its newly announced personal, wearable airbag looks like a cool fanny-pack and weighs a mere 1.1 kilograms (2.4 pounds) -- but springs forth in one-tenth of a second when sensors detect you're headed for the floor, protecting your head and ass with two inflated bags that contain 3.9 gallons of gas each.
Unfortunately, safety comes at a price. And that price is $1,400. Are grandma's delicate bones worth the cost? Hint: Duct tape and pillows.
Thanks to Julian and Ross, who both threw themselves down the stairs wearing bubblewrap jackets and lived to tell about it.
