Add saving a life to the list. 18-year-old Sam Ray was working under his truck on July 2nd when the jack gave way, sending the nearly 5,000 pound truck crashing down on top on him. With his arms trapped, Ray yelled for help, but nobody was able to hear him. That's when he heard the familiar Siri activation coming from his phone that was in his back pocket. Realizing it was a chance for help, the man was able to "push up on his hip" to activate Siri and requested a 911 call. He finally heard dispatchers on the line and received the help he needed. "When I heard a woman talking from inside my pocket, I just started shouting," Sam says. "I didn't know if she could hear me or not, but I heard her say that help was just around the corner." Trapped for about 40 minutes, Sam suffered three broken ribs, a bruised kidney and second & third-degree burns to an arm that was under the truck's exhaust pipe. Vanderbilt University Medical Center's trauma team, LifeFlight and Rutherford County EMS, Sheriff's and Fire responded and are credited with helping Sam, but "Siri" also gets credit for the "butt dial" that helped make saving him possible. Sam says he plans on attending Tri-State Baptist College in Mississippi this fall and wants to be a minister. He says he doesn't know what the future holds but "I would love to help people the way I was helped. This has reminded me how fragile life is and how little time we have to make a difference."
