For 10 years he ordered pizza from the same place. He stopped calling for 11 days, and the workers became alarmed. That simple detail saved his life.

Kirk Alexander, a man from Salem, Oregon, for almost 10 years faithfully called the same Domino’s Pizza branch to place his nightly order. But in May 2016, the phone stopped ringing.

Exactly 11 days of total silence went by, setting off the employees’ alarms. The manager did not ignore her hunch and sent a delivery driver to his house.

Upon arriving, he noticed that the television was on but no one answered the door. They called 911, and rescuers found him lying there suffering a serious medical crisis. Literally, his daily routine literally ended up saving his life.
