Joe and Clyde: Lung transplant brothers

Clyde Conn and Joe Gammalo, both 73 now, didn't know each other when they were diagnosed with the same unknown lung disease. After being put on the transplant list in December 2007 and May 2008 respectively, they both received a call on July 31, 2008 that they would be receiving one lung each from the same donor.

The two share a unique bond and have become what they call "lung brothers."
