Elementary school? By now, cracking my knuckles is as deeply embedded in my lifestyle as applying lip balm when my pucker feels dry or eating when I’m hungry. I don’t even remember when I first started. I’ve been popping my fingers, back, neck, and other appendages for years. And I know, my knuckle-cracking habit isn’t exactly flattering.
“Doesn’t that hurt?” “It will give you arthritis!” “That’s the most bone-chilling sound in the world.”
