Young motocross racer silences competition again

Editor's Note: In the Human Factor, we profile survivors who have overcome the odds. Confronting a life obstacle – injury, illness or other hardship – they tapped their inner strength and found resilience they didn't know they possessed.

This week, Dr. Sanjay Gupta introduces you to a remarkable young women named Ashley Fiolek, who won her first national motocross championship in 2008 - her rookie year.  Less than two weeks ago, she became the national champ for the fourth time.

Fiolek quickly became a role model for many girls who love this sport. Not only is she good at it, she does it without being able to hear her competitors.  Fiolek was born deaf.

She tells ESPN that this was her final season racing in the women's outdoor motocross (WMX) series, but she's not retiring.  She will continue to compete in the X-Games and hopes to branch out,  including possibly racing against men and maybe trying something new, like truck racing.
