Of bats and vampires
The myth of the vampire is centuries old. This creature was variously described as a blood-sucking fairy, snake-like with the head and torso of a woman or more often as a shape-changing humanoid creature. Most important and terrifying was its predilection for human blood and the fact that it was un-dead. Read John Mann's book review of Vampirology.
Accidents happen
Accidents happen, cynics might say, but safety experts insist that accidents don’t happen by themselves. More likely, they are caused by somebody who could have acted differently and thus averted the accident. Even if they are the result of an unlikely coincidence of several inconspicuous contributing factors, there are likely to be several switches that could have been flicked the other way and stopped disaster from happening.
