Inventions that could change the world

Husband-hunting bra  

This invention came from Japan. The "Marriage-Hunting Bra" has a digital screen that shows how much time its owner has until her 30th birthday. There is also a holder for a ring, and the countdown stops when a ring is inserted. The bra also includes a holder for a seal and a pen — the inventor took good care of those who like to sign contracts and agreements before getting married.
