Two porn stalwarts. Buck Adams, brother of porn actress Amber Lynn, died in 2008 of complications from a heart failure. He was 52. A former boxer and bouncer, Adams starred in over 600 porn films, and directed about 80. Sharon Mitchel (55) retired from the adult industry in 2003 after a career spanning two decades. She appeared in nearly 200 movies and directed 38. For 16 years in her career she was a heroin addict, but eventually quitting the habit. She is bi-sexual. That's all, folks. Thanx.
