Zac Hall, 9to5Mac:

Scott Killian never imagined his Apple Watch might save his life, but that’s exactly what happened a few weeks ago when he had a heart attack in the middle of the night. Killian recently shared his personal experience with 9to5Mac, and the details of his story are absolutely amazing.

This is a great story, worth reading and sharing. A tremendous side benefit that ships with your Apple Watch and a sign of the health benefits to come as this technology matures.
