Just wondering if anyone knows whether this is indeed true or if it''s a mere old wives'' tale. When I was younger, I used to love the sound of my knuckles cracking and persisted in doing it despite my mum warning me that it would make them bigger. Now that I''m older, I''ve stopped this habit but I''ve noticed that my knuckles are significantly bigger than the rest of my fingers! Does anyone have the same experience?
