Fright

In The Sims 2, Sims can be frightened by a ghost, or by opening up a Vampire's coffin while a Vampire is inside. Upon being frightened, the Sim's needs will drop drastically. They jump up in the air, fall back down, and check their pulse. They realize they don't have one and then collapse (and die)

Children can be frightened in this way, but will not die as a result.

instead they will either wet themselves or temporarely
