-- 
The word "leader" is derived from the word "lead", as in the material that
bullets are made out of.  The term "leader" was popularized at about the same
time as the invention of firearms.  It grew out of the observation that the
person in charge of every organization was the person whom everyone wanted to
fill with hot lead.
   I don't recomment this; it's just a point of historical interest.
