Yes, even nail guns. According to his fiancee, Gail Glaenzer, Daunte Artullo of Chicago is doing well, says bbc.co.uk. “‘He moved all his limbs, he’s talking normal, he remembers everything,’ she said. ‘It’s amazing, a miracle.’ Ms Glaenzer said she had no idea the nail had entered his skull when she cleaned a cut on his forehead. She convinced him to go to the hospital after he felt nauseous for much of Wednesday. Mr Autullo thought that the nail gun had simply hit his forehead, but realised later that when the gun came in contact with his head, the sensor recognised a flat surface and fired.” Maybe Mr. Artullo will, at some point, be able to explain how his forehead came in contact with the nail gun in the first place.
