Nope! I've been banged around sooo many times, but I get TONS of calcium so my bones are very strong.

My friend broke one of her arms six times and her other arm once. The second time she broke her arm she was just a toddler, and she actually ripped the cast off of her arm while in her crib. It didn't set properly and they had to re-break it. My mom smashed her elbow on the coffee table and now she has a chunk of bone floating around lol.
