Why don't my joints crack like they used to?

Some mod’s going to say “go see a doctor.” Whatever. It’s nothing life-threatening.

My whole life I’ve been able to crack pretty much everything which is crackable. Knuckles, elbows, toes, neck, back, you name it. If it can be cracked, I can crack it.

I especially miss being able to crack my back. It feels like it really needs to be cracked but I can’t anymore. I used to be able to just twist around and crack what felt like most of my spine, and it felt good. Now I can’t.

Any reason I can’t crack my crackables? Anything I should be worried about?
