Weeks before he died, Bob Saget opened up about the tragic death of his sister

Behind his witty persona in front of the camera, actor and comedian Bob Saget was haunted for years by the death of his older sister. Just weeks before he died, Saget spent a day with CBS News chief medical correspondent Dr. Jon LaPook, speaking about his sister Gay in one of his final interviews.  

Gay Saget died from scleroderma, an autoimmune disease where excess collagen causes tissue to lose its elasticity, in 1994. She was 47. The comedian and LaPook discussed the disease and how Saget used humor to cope with his loss.  

"It was a three-to-four year process, and she was gone. And I couldn't bear it," Saget told LaPook in December. "I can't get the images of the end of her life out of my head, ever."
