Apple Watch’s features had bee considered as smartwatch, notification provider and fitness tracker. A new feature of lifesaver has been listed recently as the Apple Watch helped to save an American teen’s life.

Paul Houle comes from Massachusetts and he suffered chest and back pain after a football training session. Then he used the Apple Watch to keep tracking on his heart rate.

When the Apple Watch statistics showed his vital signs reached at an alarmingly high 145bpm for two hours after the football session, he went to the hospital. It turned out he was diagnosed with rhabdomyolysis which was triggered by exercise that can cause muscles to deteriorate and seep proteins.

Being in an interview from CBS San Francisco, Paul Houle told the reporter that he was dehydrated and his muscles started to break down and release a protein into his blood stream which led to his heart, liver and kidneys all to shut down.

Pual Houle spoke highly of Apple Watch’s life-saving capabilities during the interview.  Apple CEO Time Cook made a personal call to Paul shortly when he heard about his story.

In addition to this, Tim Cook promised  to give Paul Houle a new iPhone 6S as well as an offer of a summer internship with Cupertino-based company.
