Well, if you've regained the use of your arms and legs, run on down and pick one of these up. An airbag for your head.

Called the Hövding, the airbag is contained in a bag that you wear around your neck. The bag also contains helium to inflate the bag, and a series of sensors to determine just when it needs to be deployed. When inflated, the bag is able to cover virtually your entire head. It can also be charged via USB and has updatable firmware, to ensure that the safety of the device is ever improving.
