Is it actually bad for you to crack your knuckles?!
Question: no not at all
Answers: no not at all
The actually cracking off the joints isn't bad for you, and actually lubricates the joints in a way, however, the excesive movement of the joint can lead to arthiritus. So, cracking your fingers can lead to joint issues, but it isn't directly related to the cracking of the fingers.
Yeah.. it cozies rheumatism
