Remember this before you decide to pull a brilliant Halloween prank to scare the hell out of someone . . . like by popping out of the closet with a knife when your girlfriend thinks she's home alone.
--It actually IS possible to scare someone to DEATH.
--If you shock someone really effectively, and it triggers a huge surge of adrenaline, there's a slim chance you could stun their heart so badly it stops beating. And the person can be young, old, healthy, or sick.
--Women are much more likely than men to die from being scared to death. It's estimated that about 1% of men and 7% of women who have heart attacks suffer them because of the adrenaline burst that comes from a shock.
--But again, the chance is VERY slim that you'll scare someone to death. Still . . . the chance ISN'T zero.
