>Playboy founder Hugh Hefner, who helped usher in the 1960s sexual revolution with his groundbreaking men's magazine and built a business empire around his libertine lifestyle, died on Wednesday at the age of 91, Playboy Enterprises said.
>"I'm never going to grow up," Hefner said in a CNN interview when he was 82. "Staying young is what it is all about for me. Holding on to the boy and long ago I decided that age really didn't matter and as long as the ladies ... feel the same way, that's fine with me."
