Scientists from MIT have created a suit that makes its wearer feel like they're 75. A large number of people in the United States will be around that age really soon, due to the baby boomer generation aging.
What would you use this suit for? It's meant for architects, store designers and other people that have to design things for older people. There will be a disconnect between the younger people building everything, and the older users. This suit will allow them to bridge that gap. It will help young people test drive their designs in an old person's body, so to speak.
How does it work? It has giant rubber bands that keep your arms stiff and you can't extend your extremities. A helmet keeps your spine curved in an uncomfortable position. It even comes with glasses that give you poor vision.
