Supermodel Christy Turlington (L) announced December 5, 2000 on ABC's "Good Morning America" that she has early stage emphysema. While working on a documentary about smoking with ABC News' Dr. Nancy Snyderman (R), Turlington agreed to take an advanced test that looked at her lungs, revealing the condition. She had already become an anti-smoking crusader after losing her father to lung cancer in 1997.
