"There is no evidence that cracking knuckles causes any damage such as arthritis in the joints."
- Johns Hopkins Arthritis Center
"Knuckle "cracking" has not been shown to be harmful or beneficial.
More specifically, knuckle cracking does not cause arthritis."
Now, I did read that it could be a subconcious nervous symptom,
and that makes sense to me.
WebMD suggests that whatever your subconcious habbit may be,
nail biting, knuckle cracking, cuticle picking, chronic coughing, or throat clearing,
they have three tips to helping you quit:
1. Make it concscious.
Start trying to figure out when you do it and why you do it.
2. Write it down.
Make a log of when you're doing it and what proceeds it.
3. Change it.
Decide on something different to replace the habbit.
Doodle or do something else with your hands.
Do you crack your knucles? (I do)
Do you bite your nails or clear your throat?
Any other nervous habbit?
I think I have lots of nervous habbits,
but I may try these three tips to see if I can change them.
