Having once sprained my back and suffered a subluxation of my 5th lumbar vertebra, I can testify to how easily it can happen. The elderly are far more prone to such problems, even though for a younger person the same problem would be shrugged off. One can raise an eyebrow at official explanations, but there is no need to sneer at a possibly truthful one, when the injury could be quite painful and debilitating. (Ever tried to wipe your ass with a strained back?)
