Ive been wondering, what's the purpose of cracking knuckles? Is it bad for you?

People used to believe that it could lead to arthritis, but that claim is unsupported by scientific evidence. There's no real benefit , however some evidence suggests that people who are chronic knuckle crackers are more prone to hand swelling and reduced grip strength. So, it may have negative impacts, but it's not the arthritic consequences previously suggested.
