Is it OK to crack my knuckles?

What's the first sound you hear every morning? Perhaps you wake up to chirping birds like Snow White, but if you're like us it's popping ankles and crackling knees. Is all that internal noise normal? Sarah King's totally unfiltered bone and joint questions include: Do men have to worry about bone density loss like women do? How can we maintain bone density? Is milk the cure for all bone and joint problems? What's the #1 thing we can do to prevent arthritis? How much damage does sitting do? The guest for this episode is Dr. Michael Ruffolo, an orthopaedic surgeon from WakeMed who admits his own joints snap, crackle and pop just like everyone else's.
