Kiss frontman Gene Simmons believes "bad decisions" resulted in the death of his former bandmate, Kiss guitarist and cofounder Ace Frehley. In an interview with the New York Post, published on Saturday, December 6, Simmons, 76, detailed his perspective. "He refused [advice] from people that cared about him - including yours truly - to try to change his lifestyle. In and out of bad decisions. Falling down the stairs - I'm not a doctor - doesn't kill you. There may have been other issues, and it breaks my heart," Simmons said.
