Bruce Willis invents concussion buster

London, (ANI): Bruce Willis has created a device to avoid head injuries on the set of his action films - a helmet made of rubber bands he calls his 'concussion buster". During an interview with talk show host David Letterman, the 54-year-old Die Hard star banged and bounced his head on the desk to prove how well the device works.

"I''m feeling a little clumsy lately. A little clumsy around the house and clumsy on the sets. You know, you get a little kicked in the head sometimes, banged around," the Daily Star quoted him as saying. “I''m getting a little older so I was fooling around the house and I get one of those little rubber band balls. This protects my head. I like to call it Bruce Willis'' concussion buster," he added.
