What about real facts?    
Joints are the meeting points of two separate bones, held together and in place by connective tissues and ligaments. All of the joints in our bodies are surrounded by synovial fluid, a thick, clear liquid. When you stretch or bend your finger to pop the knuckle, you're causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume. And as we know from chemistry class, with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking.

Why. Why does everything about our bodies explained in full detail make it sound like everyday things are going to kill us?

This is why rheumatic isn't caused by cracking knuckles. Infact, it's a stress reliever

You shouldn't use .gif for images on funnyjunk. Can't enlarge them.

Thank you so much for explaining that, I've been wondering for years, but never cared enough to look it up.

I've been trying to convince my family that cracking my knuckles won't lead to Arthritis and now I have a valid argument! Thank you.

My Anatomy Professor this semester said that this was still held as theory and that ->something or another <- had somewhat disproved it and that it's currently still up for debate.

Of course they say that for everything.

Not trying to rebuke you or anything. Just that apparently it's no longer completely considered to be the true reason.

Yeah real facts get thumbs as well, but the difference is they are real, not made up to gain thumbs from anonymous people.

Thanks a lot, OP. I just ran out of cereal so I thought I'd rip all my fingers off to access that sweet, sweet Rice Krispies marrow you were talking about.

And now I just feel like a silly Billy.

Also, I typed this with my tongue.
