What Really Happens When We Crack Our Knuckles?

Every time we do it, we love it, but why is it that every time we crack our knuckles we're met with warnings of arthritis and bone fractures.

However, we've got some research for you, becayse it has more to do with tendons, and an egg-like yolk between your joints when it comes to that 'popping' sound than it does with fractured bones. The below video will explain it all in a lot more detail, especially when it comes to long-term effects, like a man who chose to only crack the knuckles on one of his hands, in order to see how it affected his bones and hands over the years.
