Cracking Joints
Cracking or popping of joints is the action of moving joints to produce a sharp cracking or popping sound. This commonly occurs during deliberate knuckle-cracking. It is possible to crack many joints, such as those in the back and neck vertebrae, hips, wrists, elbows, shoulders, toes, ankles, knees, jaws, and the Achilles tendon area.
Famous quotes containing the words cracking and/or joints:
“Hume’s doctrine was that the circumstances vary, the amount of happiness does not; that the beggar cracking fleas in the sunshine under a hedge, and the duke rolling by in his chariot; the girl equipped for her first ball, and the orator returning triumphant from the debate, had different means, but the same quantity of pleasant excitement.”
—Ralph Waldo Emerson (1803–1882)
“Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.”
—Walter Benjamin (1892–1940)
