I can't believe there is a website for joint crackers!! That is so cool. I am a 22-year old obsessive joint cracker. I crack my knuckles, wrists, neck, back, knees, ankles, toes– everything I can. I sometimes spend 30 minutes or more just cracking my knuckles. I love cracking my joints; it's almost like a drug. Well I hope to meet other obsessive joint crackers!
