                      Trying to keep your mouth closed while
                     yawning is not just good manners - it might save
                     your life. Ben Shire, 34, was making a cup of tea to
                     keep himself awake when a massive yawn took
                     hold. Within seconds, the father of three had
                     strained his jaw so much that he dislocated it.
                     He collapsed on the floor, unable to breathe or
                     swallow. His wife dialled 999 as he lay on the floor
                     choking on his saliva. Paramedics rushed Mr
                     Shire to hospital, with his jaw still locked,
                     where medics resuscitated him using a suction
                     device. It then took doctors four hours to reset his
                     jaw. "We can laugh about it now, but it wasn't
                     funny at the time," the store worker, from
                     Horsham, Sussex, said.Related Articles  "I couldn't breathe because I was choking -
                     it felt like two fingers down my throat. The
                     more I panicked, the more I struggled for
                     breath." His wife Sam, a hotel cleaner, added: "I was
                     really panicking and didn't know what to
                     do." A spokesman for East Surrey Hospital in
                     Redhill praised the quick thinking of the
                     ambulance crew. Cases of jaws locking open mid-yawn are very
                     rare. Doctors advise people who do experience
                     the problem to bend forward or lie on their side
                     in the recovery position to let gravity ease the
                     pressure. People with locked jaws can feel like they
                     are choking because of the build-up of saliva in
                     their mouths. To reset a locked jaw, dentists push the
                     lower jaw downwards and back by pushing on the
                     lower back teeth.  |
