Works as a form of torture as well.
How about a small wrist device that checks the (insert whatever gets produced when you get angry in your body, IANAD) levels in your body and quits according to that?
That would quit when YOU get salty.
I wonder if that would even be possible, you can’t just use the increased heart rate, as that alone can mean different things. Wouldn’t want the device to shut down your Dark Souls just because you’re fighting a boss…
