As the country with one of the fastest rising elderly populations on the planet (a whopping 22 percent of the population is over 65) Japan's innovators have begun planning for life in a mostly grey society. The latest invention geared towards such a reality is the human airbag. Developed by Mitsuya Uchida, the president of Japanese firm Prop, the device was originally designed to help elderly citizens with epilepsy.
The airbag deploys in just 0.1 seconds when sudden falling motion is detected, protecting both the neck and torso areas. Despite the somewhat humorous effect the device offers visually, at 138,000 yen ($1,290) this is probably one of the most thoughtful giftsyou could give the elderly loved one in your life.
