In the 2000 film Unbreakable, the hero survives a fatal train wreck without any injury because of his super-strong bones. But this superpower can be matched by a family in Connecticut, according to a Yale study from 2002. Researchers found that these family members carried a genetic mutation that caused high bone density, which protected them from fractures.
