I lost both my parents to cancer. My father died at the time the Livestrong Foundation was formed, and I've been wearing the yellow bracelet since the beginning. When it finally became apparent that Lance Armstrong had been doping, I still wore my bracelet because I was able to separate the man from the foundation.
However, after reading that Armstrong's doping could have helped cause his cancer, I can't do it anymore. I recently threw away my bracelet. I'll find another cancer organization to support.
Imagine you have trained hard for a year for the Tour de France, but the only chance you have to win is if you dope like many other contenders. What are your choices?
