Cracking Knuckles

From a young age i learned that there are certain things you shouldn't do without being given an explanation that makes sense. One of these things was cracking your knuckles, and the reason being is that it gives you arthritis when you become old. Due to this explanation i refrained from doing such a thing. Joints are the bony parts of your body held together by ligaments that are able to bend. After taking this psychology course i realized that to learn things you must go and do some research,
Arthritis can be caused by crystal formation in the joints. Cracking your knuckles doesn't necessarily give you arthritis, but it does weaken your joints over time.
This is a clear case of how extraordinary claims need extraordinary evidence and the evidence itself proves that there is not enough information to show that cracking your fingers gives you arthritis.
