Crack Research: Good News About Knuckle Cracking

How many times did your mother tell you that cracking your knuckles would give you arthritis? If you’re like most people, it was a lot. So, is it true? Was your mother right? That’s exactly what Dr. Donald Unger set out to determine when he conducted an experiment……..on himself. For 50 years, he cracked the knuckles of his left hand at least twice a day, leaving those on the right as a control. Thus, the knuckles on the left were cracked at least 36,500 times, while those on the right cracked rarely and spontaneously. When Unger analyzed his data, he found that there was no arthritis in either hand, and no apparent differences between the two hands, leading him to conclude that there's no apparent relationship between knuckle cracking and the subsequent development of arthritis of the fingers. So, while your mother might have been right about a whole host of things, she wasn’t right about cracking your knuckles...........so, crack on!
