1 . As 17-year-old Torri’ell Norwood drove through Florida, last February, the laughter and chatter from the four teenage girls inside her car quickly gave way to screams. As they approached an intersection, another car T-boned them, sending their car sailing into the yard of a nearby home, coming to a stop only when it crashed into a tree.

As smoke rose from the car, a bystander shouted, “It’s about to blow up! Get out!” Shaken, but otherwise OK, Norwood crawled out through the window as the driver’s side door couldn’t be opened. Along with two of her friends, who’d also managed to free themselves, she ran for her life. But halfway down the street, she realized that her best friend, Simmons, wasn’t with them. Norwood ran back and found Simmons unconscious in the back seat. She threw open the back door and pulled her friend out. She dragged Simmons a few feet to safety and laid her on the ground. After checking her pulse and found there was no sign of life, she started CPR.

Had the accident happened a few weeks earlier, she might not have known what to do. But just the day before, Norwood, who wanted to pursue a career in medicine, had earned her CPR certificate by learning on her own. Kneeling on the lawn and looking down at her dying friend, Norwood knew she had precious little time to practice what she’d learned.

She started pumping Simmons’s chest with her interlocked fingers and breathing into her friend's mouth in hopes of filling her lungs with the kiss of life. After quite a while, Simmons began coughing and taking quick deep breaths for air. The CPR had worked! Soon, the ambulance arrived and rushed Simmons to the hospital. And then she heard how her best friend had saved her life. “I wasn't shocked,” Simmons told others. “She will always help any way she can.”
