Dr. Ozzy Osbourne is encouraging people to take care of their health.  Ozzy and his wife Sharon are featured in a new CBS public service announcement promoting colon cancer screenings.
The PSA also promotes the "CBS Cares Colonoscopy Sweepstakes." The grand prize winner will get a three-night stay at a luxury hotel in New York City along with a free colonoscopy at New York-Presbyterian Hospital.  The issue is personal for Ozzy and Sharon, who ten years ago was diagnosed with colon cancer.  She credits "a colonoscopy that Ozzy urged me to have" for helping save her life.
