Is my shoulder,knee,wrist,ankle supposed to crack? ?

my mum once told me she said "dont crack your knuckles or you'll get arthritis in them later on" and she also said "dont crack your bones, when they need to crack they'll crack without you forcing it" so take my mothers advice because shes right, dont crack your bones, it could cost you when you grow up, i used to crack my knuckles alot but ive stopped now, you should stop too.
