ClockworkWXVII, on Reddit:
I was laying in bed, enjoying some TV and homemade brisket, when my Apple Watch told me that my heart rate was weird af, and then, told me my heart rate was stupid fast (thank you heart rate alerts)
Called ER, when they arrived, they found me in serious trouble. Body went into shock, got rushed to the hospital in a stretcher, and got taken into trauma.
I felt totally fine before everything happened, and then notifications, and then BAM, everything goes nuts.
100% thank you apple for making an amazing accessory and tool that helps people stay not dead.
