Judy is retired and lives alone and is thinking of getting an Apple Watch. But what will happen if she takes the watch off and it doesn't feel the pulse? Will it contact emergency services? Leo says he isn't sure that it will call home in that case. Will it sense if you have died? Leo says no, there isn't. It'll detect that you have a low pulse and give you a warning, but so far, there is not a "phone home" from the watch if you die.
