Death by emotion.
I find it very odd that only Playful, Anger, and Embarassment are the only emotions that cause death. I've heard of such things as being Bored to Death, Sadness seems like a potential way for a sim to die, being too uncomfortable sounds like a way for a sim to die, focusing too much that the sims gets a stroke and dies, and Over Energizing seems like a way for a sim to explode from too much energizing. Of course, some emotions, I can't imagine dying from like excessive Confidence, Inspiration or Flirty. (Maybe too much flirty causes hormonal overload?)
