One of my habits is cracking my knuckles. Pushing finger joints, I can make a cracking sound. When I was in elementary school, it was popular among the children. Since then, it has been my habit. Thanks to it, my fingers have good flexibility. It's said that cracking knuckles makes fingers thick, but my fingers haven't been so.
