Curious - does Apple Watch call 911 if you flop onto bed and start napping away?

No. You have to really take a hit -- and you have to fail to cancel the 60 second (very loud and annoying) countdown, too.

  I can think of a lot of things you can do that will make the portion of your body that the watch is attached to take a really hard hit. How does it not have a high false positive rate?

    Exactly. If it is just detecting falling down from standing position, I can imagine several things causing that

It also considers your cardiac rhythm so I would think they trained their model to consider it.

  I hope not, I don't want my smashed head to be ignored just because my heart is still beating.

  I have not seen that mentioned anywhere. Is there a reference for that?

  My understanding is they are very specific about this not being able to detect heart attacks - hence why I'm hesitant to speculate about the exact sequence of events above

It's probably more about instantaneous acceleration. Nothing you can do with your own two arms and legs will ever cause you to experience a deceleration as hard as what happens when you fall from a standing position onto a hard surface. (Unless you ran full-tilt into a brick wall, I suppose.)

There was a good bit by Joanna Stern in the Wall Street Journal where she hired a professional stuntwoman; she was unable to trick the watch into thinking she had fallen, but the stuntwoman was able to by taking some hard falls. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=2ahUKEwiE4f64yerkAhUr2FkKHczQA5wQwqsBMAF6BAgIEAk&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DG7xI2dUPN3A&usg=AOvVaw3r0Jw_1xe2WT6AoLRmPU1H https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&c...
