What's going on
Someone went in for a routine teeth cleaning, and partway through, they noticed their dentist kept anxiously checking in, asking "are you doing okay?" far more than usual. It turned out the dentist wasn't just being extra attentive — they were reading it off a screen. The patient's smartwatch, strapped to their wrist and in plain view during the whole procedure, was flashing a big, unmissable "DISCOMFORT" reading the entire time.
The watch was running a mood-tracking feature that estimates emotional state from heart rate variability, and it had essentially ratted the patient out in real time, broadcasting exactly how much they were suffering to the one person in the room who could see it best. The post quickly drew in replies from other smartwatch owners with their own stories of wearable tech blowing their cover at the worst possible moments.
