who suffer from one A he is no fun

who suffer from one A he is no fun at all. People have a lot of pain. Sometimes it's because a vertebra (a bone in the back) is out of position. In ancient Greece doctors used to cure a backache like this: They tied the patient to a ladder, pulled the ladder up high and then let it fall to the ground. Bang! The vertebra went back into place. Well, that was the idea, but this "cure" probably just made the backache worse!
